No, this just started yesterday.... could be because I experienced another invasion of 'System Tools' virus..... don't know, but it drove me crazy for about 1 hour... I was on the verge of uninstalling Office 2010 and doing a new install... with all the bells & whistles of 2010, it seems to be a very unstable software.... those geeks at Microsoft just sit around and think of cr*p to justify not getting laid off....
