Yesterday, I noticed that my msn messenger was not opening. I would press the toolbar icon for it. The icon would do its regular jumpin up, but then stop. Nothing would open. So, it just wouldn't open. I thought this might just thought that this was a prob with the program. But then today, I tried opening my limewire, and same problem. I would click on it on the toolbar and it would jump and that's it. It wouldn't open. The same thing happened with an ofoto (third party program) program icon on the toolbar. Funny thing is all the apple programs like safari, iphoto and such load up fine. It seems to be third party programs. I also tried to open them right from the applicartions menu. Still nothing. Is there something I'm doing wrong? I'm new to macs, it's my wife's MB actually.
