Well, of course their are extentions in System 10. Not in the same way as under 9 but... DefaultFolder for example, QuickKeys, Suitcase etc etc. Maybe there is a conflict there. Maybe. I only have crashes in Vue from time to time when i click to quickly from one window into another. The display handling seems to be a little "sensitive" sometimes. Anyway, if you want me to, i can make a screenshot of my settings tomorrow (when i am back at the office) so you can compare.
