I posted this problem in another forum, but perhaps it's more likely to get a response here !? I've installed Final Cut Studio on my Dual Core G5, with Leopard, and only Final Cut Pro and Color will open properly ! All the other apps open with an empty apple menu, so no options to Quit, save,... anything. Oddly they also open with no serial number or version number in the title card when opening. I have to force quit them. Sound Track Pro also come up with the "Unexpected Problem" message: NSInvalidArgumentException *** -[NSCFDictionary initWithObjects:forKeys:count:]: attempt to insert nil value at objects (key: NSCTFontCharacterSetAttribute) Anyone else running this same set up and having problems ? Or having no problems ??? Cheers.
