Hi,
We have 2 copies of Omnigraffle 5.1.1 one works fine, the one I bought today refuses to do a few things, in particular the changing from canvas to outline. Gives this error:-
It might be the Mac but I can't see why, its a G5 running 10.5.6.
Reinstalled 5 times with no luck, only bought it today so any advice would be great as its unusable at present!
