Hi, I have some problems using SoftICE debugger. When I press ctrl-D, SoftICE window didn't show up ,and desktop seems to hang. I used to run WinXP virtual machine on VMWare ,and there's a solution for this issue. For VMware users, to add "svga.maxFullscreenRefreshTick = 5" to the configuration file can fix the issue. More details:http://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=965 I am wondering if there's any corresponding solution for Parallels Desktop.Any help will be greatly appreciated. My environment: Parallels 8, Windows XP x86 guest with SP2,and the latest version of MAC OS. Many thanks.
