Since about 5/4/2010, Excel 2007 has started taking from 20 to 45 seconds to 
quit after I select exit. I read about cleaning out temp files for slow 
opening so tried that but no help there. No updates were applied, it just 
started to slow down and affects files that have not been changed - even just 
starting Excel and then quitting with no file open. Watching task manager I 
can see excel working and using 5 - 10 % of the CPU after slecting exit.

Any suggestions please?

Thanks
