Dear Users, Parallels Desktop 4.0 Build 3540 is available for download: http://www.parallels.com/download/desktop/ IMPORTANT! - This is English build and won't work with localized activation keys. Localized builds will be available soon. Bugfixes and improvements: Improvements in the upgrade procedure: - BSOD in Boot Camp with the "Autochk not found" message followed by the session manager crash - fixed. Note: If you see this BSOD in the release version of Parallels Desktop 4.0, open the virtual machine configuration, select Hard Disk 1 in left pane and click OK. This will prevent this BSOD in the virtual machine and the Boot Camp partition. - BSOD with the "0xA5" message during the virtual machine upgrade - fixed. Note: If you get this BSOD in the release version of Parallels Desktop 4.0, convert the backup copy of your virtual machine. Before convering the copy create one more backup copy of it. - Windows stops on boot during the upgrade without any crashes - fixed. Note: If this error occurs in the release version of Parallels Desktop 4.0, convert the backup copy of your virtual machine. Before convering the copy, create one more backup copy of it. Alternatively, you may add the "vm.compat_level=2" string to Virtual Machine Configuration > CPU > System Flags (make sure that the "show advanced settings" option is selected). - Virtual machine crashes on start after the conversion - fixed. - Possible causes of BSOD in intelppm.sys and agp440.sys - fixed. - Mouse is not available when upgrading a virtual machine that was originally created with Microsoft Virtual PC - fixed. - The sound is disabled in Windows XP virtual machines after the upgrade - fixed. - Hard disk cannot use the Boot Camp partition after the upgrade - fixed. Note: If this error occurs in the release version of Parallels Desktop 4.0, open the virtual machine configuration, select Hard Disk 1 in left pane and click OK. - The message "Failed to configure the Boot Camp partition" appears after the upgrade - fixed. Note: If this error occurs in the release version of Parallels Desktop 4.0, open the virtual machine configuration and click OK. Other improvements: - At times Parallels networking drivers don't start after the restart of Mac OS X - fixed. - Copy-paste operations may fail in some cases when the virtual machine is in Coherence - fixed. - Copy-paste operations may fail in some cases when non-text data is being copied to Windows - fixed. - Inability to switch to a Windows application using Application Switcher when the virtual machine is in Coherence - fixed. - Redundant network icons appear in the Mac OS menubar after switching between the view modes - fixed. - Mac applications stay on top of Windows applications in Coherence - fixed. - USB performance improved, including the ability to sync iPhone with iTunes installed in Windows. - Dispatcher service binding to all network addresses on port TCP 64000 - fixed. - The ability to suspend a Boot Camp virtual machine was removed, because this operation may damage the Boot Camp partition. - .NET applications menus drawing in Coherence - improved. - Crashes in virtual machine monitor and the application based on the statistics received through the problem reports - fixed. Known issues: - A message "hal.dll is missing or corrupt" may appear when you use the Boot Camp partition natively if the Boot Camp virtual machine was shut down incorrectly in Parallels Desktop 3.0. To toubleshoot this issue, edit the boot.ini file to be able to log in with a proper user profile. - Removing the virtual hard disk from the virtual machine configuration and then adding it again results in moving the hard disk to the last position in the virtual machine's boot order, which seriously increases the boot time. To troubleshoot this issue, edit the boot order in the virtual machine configuration after readding the virtual hard disk. - Control Panel may be unaccessible in Windows Vista loaded from Boot Camp. - Scheduled chkdsk may fail to start on Windows Vista booting in a virtual machine. - Parallels Desktop may start consuming up to 100% CPU after setting 2 CPUs in a Windows virtual machine configuration. To troubleshoot this issue, update the CPU driver in the Windows guest OS. - A Windows Vista Boot Camp virtual machine may request to be activated again after upgrading to Parallels Desktop 4.0. - The maximized window of a Windows application may cover Windows taskbar in Windows virtual machines that were converted from Parallels Desktop 3.0 format. To troubleshoot this issue, right-click the Windows taskbar, select Properties and enable the "Keep the taskbar on top of other windows" option. - All guest operating system windows are minimized after switching to another Space. To troubleshoot this issue, switch the virtual machine to the Window mode and then back to Coherence. - The virtual machine will not change its IP address after switching from the bridged wired to wireless network and vice versa, which may result in the virtual machine's disconnection from the network. To troubleshoot this issue, right-click the networking icon in the guest Windows operating system and click Repair. - The Parallels service user profile may remain in a Windows virtual machine after the upgrade to Parallels Desktop 4.0 is complete. - Parallels Transporter and Parallels Mounter are unable to work with Boot Camp partitions. - You cannot revert to snapshots that were created on 32-bit Mac host computers and resume virtual machines that were suspended on 32-bit host computers with Parallels Desktop installed on 64-bit Mac OS host computers, and vice versa.
