Was typing an email last night with Windows Mail when all of a sudden it vanished & the desktop appeared then back came the email etc.  A few minutes later happened again but it was back in a flash this time. 

While doing other things on the computer have had it happen also.  I have IE 8 & Windows Vista so wondering if it's one of the little hassles with IE 8.

Not sure what you have going on, but IE8 certainly would not be the cause of a issue with your email. sounds like you hit a key stroke to minimize, then maximize windows mail.

8

Is there a key stroke other than the min & max up the top that will do that.  Was just typing away but with me anything is possible.   I did forget to say, after it happened & the other times an error window appeared saying "Super fetch has stopped working"  with the choice to either look for an answer online or forget.  Cannot remember the exact words but the same message each time.

I would have thought if I accidentally hit something I would have had to click to bring the WM page & the email back up but they came back almost as fast as they went.    A few times I have been typing away & looked up & nothing has written & the curser seems to be frozen.  After about 30 seconds it comes right again.

I have run scans to see if I have picked up anything nasty but all OK.

Thanks for that.  Went there & read what it had to say.  Understand nothing to worry about. 

Did a diagnostic health report & it says  Symptom: D:has lesss than 15% free disk space.    Cause: a logical disk has a low amount of free space.   Details: D: has 1037 MB free disk space, there is 13% free.  Emptied the recycle bin & cannot seem to get more space.  Any ideas on what to do?  Annoying everything being so slow.
