Hi everyone,
I have just returned from a weeks holiday and am also experiencing a similar problem. Everything was working correctly before I went away but it is jammimg at 36% just after it finishes deleting browser history panel that comes up ( somthing I hadnt noticed before I went away) the c cleaner has jammed showing c:\windows\MEMORY.DMP with the spinning orb. I am too running Vista SP1 and use IE 8 as default browser. I have auto updates for and for CCleaner and think were some updates to both before i left. Any advice to solve this would be helpful.
