Hello, I have recently tried to develop an iPhone app using xcode and interface builder and I am really unable to do anything due to this one issue I've been having. XCode opens fine and I can do whatever I want there. When I click on MainWindow.xib on the side to open a preview of my app it still is ok, the problem I encounter is when I scroll down about halfway in the library on the right, the program freezes from there on out and I need to force quit. I've searched through the forums and didn't find anything on this, and when I googled it there were some people with similar problems but never a solution to this. Please help! Thanks.
