Hi,
I'm on 10.6.3 with the latest OmniGraffle

Product: OmniGrafflePro-5.2
Tag: OmniGraffle/5.2.2/release-138.14
Date: 2010-03-22 13:34:48 -0700
Builder: ryan
Host: tb105i.private.omnigroup.com
Revision: 129428

I just started using it today on this system and am constantly getting alerts saying:

_endUndoGroupRemovingIfEmpty:: NSUndoManager 0x97e020 is in invalid state, endUndoGrouping called with no matching begin.



This happens every several actions I perform requiring constant clicking to clear the alert box. Needless to say, it's causing my productivity to plummet. Is there anything I can do to prevent the alert messages from appearing?
