i have recently installed .net framework v3.0 and every time i log off or shut down my computer i recieve for a short period of time a message saying that a program is not responding and that win is ending it now(when i close it)
its called .net broadcast something or .net event reciever.....one or the other or sometimes both
this messages appears for maybe a second or two so i do not know their exact names because they dont fit into that ending program window
how can i solve this problem?
is there some online help or troubleshooter for this program as i am unable to find it on my comp and i refuse to believe that it hasnt been done

thanx
