At one point Messenger 8.5 would load two copies, one not completely though and freeze, but mostly even if it loaded when I started a video call with my friend at one point before his video a second window would come up, my picture would freeze, while hearing each other.
Also the main window would go blank every now or then. (White in the inside).
Yesterday I upgraded to IE 7 thinking that I may have allowed a registry cleaner to butcher IE figuring I was'nt
using it anyway...
But today I say a double window for a few seconds, so I believe that the doubling issue is still there.
I will be uninstallin Bitdefender 2009 tomorrow, I upgraded lately and it is a bugridden piece of junk, I have 5 months left from my subscription, can't wait to dump it. That always can be a culprit too.
