I installed Vista SP2 (from MS CD) over XP Pro and it's become a freekin'
nightmare.  Don't mean to sound nasty.  But man-oh-man it's not been pretty.  
It took 7 hours to install and then another 24 to get my system to boot
without errors successfullly, and it still does boots with errors, half of
the time.  Rebooting is no quick process with Vista.  I'm almost crippled.  I
overinstalled my existing Op Sys because I have so much software ... and you
all know it takes forever to reinstall everything.  

Another problem ... everytime I click on anything ... and I mean anything, I
get a "windows install" window that displays.  What is it doing?  
      At first I thought it was trying to access my behaviour and install
on demand, but it doesn't stop.  I just installed three days ago.  This
"windows install" screen has displayed probably a thousand times ... and
continues to display when I click something.  All the updates are already
installed, so it can't be updates.  

Any thoughts or suggestions.  

     I want my system to work and don't mind testing and working through
this (I know it's not perfect ... it's a beta) but this is making me a little
crazy.  I just don't know what my pc's going to do next when I boot it up.  
It often gives me "explorer" errors and then it just stares back at me with a
blank gray screen ... there's no option to shut down.  I've had to powered
this machine down soooo many times ....

So ... would you like some cheese with all this whine?

Thanks for any insights.
