I had a similar situation with a graphics viewer I was writing, where I wanted the user to be able to drag and zoom the image with the mouse, or by scroll bars. I haven't yet had a chance to solve it myself, but I believe it has something to do with blocking signal emmisions. I do agree, there should be some more mention of this situation in the documentation and/or FAQ's. I'll also be watching this thread for suggestions on how to solve the problem "the proper way"...
