Hi friends, I am Ichiro (near Tokyo), using Parallels Desktop 2.5 build 3214 (Japanese). I have been experiencing clock delay in DOS BOX of Windows XP Home (Japanese). Clock of XP is synchronized to MacOS X clock at any time. When I start a DOS BOX to run a simple DOS software that uses OS clock, the clock for DOS box is synchronized to Windows XP at first. After only 10 minutes or so, the clock obviously delays. Maybe I got 3 minutes delay in 10 minutes. Is there any workaround? Any advices are greatly appreciated. NOTE1: The difference between Parallels Desktop English and Japanese is not basic functions but fancy issues (menu, help instructions, etc.) as far as I believe. NOTE2: I have done a brief search in the site but I may miss something related articles. My language at home is Japanese so have some difficulties. Japanese representative for Parallels didn't helped for my technical help that I submitted a few months ago.
