Though by a small number so far, it is seeming people with Vista are fine … and people not, are not.
Is there any reason you don’t keep an XP machine around, Frits? I daresay most people still use XP, and Vista and XP are not entirely cross-compatible (if that’s the term). In order to be sure, I think it a good idea to keep both Vista and XP available for, at the very least, quick testing.
With that said, I totally understand it’s not solved yet, more people would need to chime in with their OS and results. ’twas merely a preliminary comment.
