I think this has been happening since I used a program to delete all of my unneeded languages but I'm not quite sure. Basically a few of my apps simply don't open anymore. I'll double click on them and all that happens is they'll appear in the dock, maybe get to half a bounce then disappaer. That's it. I have no idea what to do. It's happened with LimeWire and aMSN, my httpMail plugin has stopped working. I just downloaded RealPlayer and same thing happened. I'm on a 1.83GhZ MBP, had the laptop about a month or two, never had any problems like this. Any ideas?
