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"...
