I am running a CAM program called OneCNC, have been using it on 2.5 without problems. (Well, until 10.4.10 killed the USB dongle function anyway). Upgraded to Parallels 3.0, latest build, everything works well *except* the OneCNC toolpath simulations. In this, they open a separate window and animate the toolpath for a CNC mill. When it does this, all kinds of strange things happen: the window is very slow to open, the animation very jerky, the toolbars at the top and bottom of the window are in the wrong place and blink rapidly on and off, sometimes disappearing altogether, when the window is dismissed pieces of it hang around for up to a minute before they are refreshed away. None of this happened on several builds of 2.5. Everything else is identical. I have tried all the settings in the VM configuration I can think of. It happens in an OS window, full screen, various screen resolutions.
Any ideas? Just a bug in 3.0? Why would it be that different?
Edit: I should add, this is the older MacBook Pro, 10.4.10, Windows XP Home SP2
