Dear Users, Parallels Desktop 4.0 Build 3810 is available for download: http://www.parallels.com/download/desktop/ What's new DirectX 9.0 with Shaders Model 2 support Windows 7 inside the virtual machine (experimental) Apple remote disk support Silent start in Coherence Possibility to drag Windows files to Mac applications in the Dock Possibility to remove a virtual machine from the list with a context menu option Possibility to specify CPU and memory options in the New Virtual Machine assistant Possibility to suspend Boot Camp virtual machines with the help of the "disp.allow_to_suspend_bootcamp_vm=1;" system flag Snow Leopard as a primary operating system (experimental) Snow Leopard as a guest operating system (experimental) Customer Experience Program SSE4 support (better performance for media applications) Bugfixes and improvements General performance improvements. Improved USB support (performance, USB1.1 compatibility fixes). Better performance of Suspend/Resume operations Improved hard disk performance for virtual machines converted from Parallels Desktop 2.5 and 3.0. Memory leak in Parallels Desktop GUI that might happen after 1-2 days of work fixed. Accidental crash in Redhat Linux 5.2 Server x86_64 during installation fixed. Problems with connecting Palm handheld devices via USB fixed. Improved sound playback via USB devices. Empty keyboard remapping in the clean PD4 installation fixed. Networking issues when the Mac network location changes fixed. Timezone and daylight saving time were not synchronized in the virtual machine with time synchronization enabled fixed. AltGr keyboard mapping issues on European keyboards fixed. Parallels Tools installation hangs during the virtual machine upgrade fixed. Failure to configure the Boot Camp partition with Windows XP SP0 installed fixed. Releasing input of a Logitech mouse when rolling the wheel in a non-Coherence mode fixed. Impossibility to view the configuration of suspended virtual machines fixed. Duplicated MAC addresses for virtual network cards when a virtual machine is added to the list fixed. Boot Camp virtual machine hangs on reboot after the second stage of upgrade fixed. Wrong CPUID emulation resulting in poor performance of Mac OS X guest OS fixed. Host computer performance issues when many CPU are intensively used in the guest OS fixed. SMP guests affect host Mac OS X performance noticeably fixed. Time going slow in Windows guest OSs on some workloads fixed. Long upgrade from Parallels Desktop 2.5 and 3.0 caused by the hanging or reboot of a process in the guest OS fixed. Issue with 'chkdsk' in a Boot Camp virtual machine users of existing virtual machines need to reconfigure existing Boot Camp virtual machines fixed. Delayed Parallels Internet Security installation: a prompt will appear 3 days after the virtual machine installation. Lower CPU usage inside the virtual machine resulting in longer battery life. Disabled UAC (user access control) in Windows Vista after upgrading from Parallels Desktop 2.x or 3.x fixed. The Parallels Tools uninstallation now automatically disables the shared profile. Broken scrolling in Java applications with Parallels Tools installed fixed. Broken Dock icons in Snow Leopard fixed. The case sensitivity problem of the shared folders file fixed. Shared folders do not list some files if a folder has too many files fixed. Known issues Mac OS X 10.6 Snow Leopard x86_64 issues: - No shared networking support use bridged networking instead. - No USB support. - The performance of SMP virtual machines may be degraded. Windows 7 experimental support issues: - Windows 7 x86_64 installation media cannot be automatically detected. - No sound support. - The virtual machine screen stops being redrawn if the Windows Energy screensaver is run. Dynamic resolution might not work in a Linux guest OS with the default amount of video memory. It might be necessary to increase the video memory size to at least 6 MB to let the feature work. Time difference is not saved between Mac OS and Linux guest even if the Allow time difference between host and guest" option is enabled. Recycle bin integration does not work if Mac OS Dock auto hide is enabled. Disk encryption tools make Windows boot extremely long. To work around this issue, add the kernel.real_mode_vtx=0 to the system flags in the CPU settings. Sound quality in Mac OS X guest is not very high. Certain 3D applications (like 3D Canvas, Autodesk Inventor, and some others) may work improperly when 256 MB of video memory is allocated to the virtual machine. To work around this issue, decrease the video memory to 128 MB. A message about ATI service that failed to start may appear in Boot Camp Windows virutal machine after booting. This message does not affect the virutal machine performance and can be barely ignored. Windows Vista in a Boot Camp virtual machine may require reactivation after upgrading from Parallels Desktop 3.0 to this version of Parallels Desktop. A wrong CPU driver is installed in a virtual machine that was initially migrated from a Virtual PC, then used with Parallels Desktop 3.0, and finally converted to Parallels Desktop 4.0 format. This results in high CPU usage in host OS with no application using CPU in the guest OS. To workaround the issue, reinstall CPU drivers in Device Manager inside the guest OS. Improper textures in Serious Sam 2 and Far Cry. Poor performance of Black and White 2. Breath of Fire 4 does not work properly in the 32-bit color mode. Problem scrolling in Punch Home Design. Apple iSight disappears from Mac OS X if connected to and disconnected from a virtual machine multiple times in a row. Apple USB modem does not work in the guest OS.
