All the thinapped apps works well without avast under WinXP Home/Pro, SP2 or SP3, Windows 7 with different graphics cards. They even runs smoothly in VMware guests (WinXP Pro SP2).
On how many systems have you tested it?
Switching graphics cards new/other drivers are installed and often causes conflicts.
I have new recoverable system errors when using WinXP explorer (maybe bad too?) that occurs randomly
Nothing ever happens randomly on a system. It may seem that way to a user, but it is not random. Things always happen when a certain (or multiple) requirement is there.
Have you tried things on a clean (and properly) installed system?
If so, what is/was the result?
