The other members are right, I too am frustrated as hell sometimes. You can select the model from the list in 'level' and turn the scene around in the 3D view window. OR move the 'block' out of the way while you work on the model, or take up knitting!!
What we need is the ability to 'hide' any item, as in MED.
We can but hope!!
If you have a specific problem, mail me (PM) and I'll see if I can come up with anything.
