I have this aggravating and strange problem with good old windows messenger. As administrator it works just fine. If I create a new limited account then messenger doesn't work. When I click on the icon it seems to start because I can see the hourglass flashing a couple times, but after a second or two it bails out, eg. just exits like that. Looking in the Windows Task Manager I can see that it is not running anymore (in the background). Is there someone out there who can help me?
