Spyder~
Yes, I couldn't even cancel the scandisk in normal mode............it had already frozen.
I increased the page buffers from 12 to 32 and that didn't help (that can help with some msgsrv32 problems ;) )
I use WinPatrol partly as a diagnostic tool as it lets you suspend programs then turn them back on a the click of a mouse.
Please let me know how you get on
Cheers
