Fix this wireframe bug please!
Until recently, I've always been able to bring up the wireframe for resizing an image in the program window by putting the playhead on the relevant clip in the sequence and double-clicking on it's image in the program window. Now, more often than not it doesn't work. It works if I have just opened Premiere and it's the first thing I try....but then it stops working. It's an infuriating bug! Please look into it and fix.
