Front Panel Bloat - crashes Labview 8.2!!! - labview

Over the course of development of my .vi, the front panel has become impossibly large and it is difficult if not impossible to locate all the "pieces".  Scrolling to the left crashes Labview.  I've tried the aligning and distributing tools, no good except they probably messed up what little formatting I had. 
 
Two questions -
 
Is there some way of zooming in and out on the front panel / block diagram?  This is one of my biggest pet peeves with the program - I get these microscopic pixel things on the block diagram, and we visually challenged old guys have a tough time seeing what is going on.  And a zoom out on the front panel would let me see the whole thing at once and easily find things to compact them.
 
Is there some way of bounding the front panel / block diagram so it doesn't continually try to create more and more space until it crashes like it does on my .vi?  Every time I try to move elements of my block diagram / front panel to the upper left - there come the scroll bars again dutifully (and unwantedly) creating more room to the upper left. 
 
Yes - I know I am probably missing .vi's - the @#$&&& form only lets me add three attachments to the post!!!!
