What common security app's likely to keep inserting kill bit in the registry in MS IE compatability flag, that keeps stopping install of Flash Player - guesses, anyone? I have that turned off in Spywareblaster; don't think it's Spywaresweeper, but I wonder is there a setting perhaps in Spybot doing this? Keep finding/deleting flag in reg., and it keeps coming back. Had read about this problem on Adobe site, and found it. Used Adobe uninstaller, to del. old versions of Flash, changed settings (properly, I think) in IE but just no luck with it.
