Hey,
I had big problems with the 10.6 Catalyst drivers and Flash version 10.1
For me, whenever any page opened up that used flash, it was an instant BSOD!!
I tried uninstalling 10.6 and using 10.5, used driver sweeper in between uninstalls of drivers. If I uninstalled all Catalyst and looked at a web page that had flash content (using default windows drivers) it worked fine. As soon as 10.6 was put on, BSOD.
I uninstalled Flash 10.1 and re-installed without it making a difference, still BSOD every time.
I did run Arma 2 and didn't notice any probs though so not sure if this is/could be related or not.
The only thing that worked for me was to track down the old 10.0.45 Flash exe and run that. As soon as that was installed again, no more BSOD...
Something for you to try to see if it makes a diff maybe.
