With multiple diagrams, selecting a diagram and then selecting the Undo menu item shows undo actions for different diagrams. This is unexpected behavior to say the least. 

Second, I had deleted the 2nd diagram before doing this, and was trying to undo some items in the first diagram as well.

How to repeat:
Make a diagram and put some tables. I had 12 visible tables.
Select all tables and do a Ctrl-C (copy command)
Start a new diagram, paste all the tables in there.
Auto arrange the old diagram (what I did, not sure it's important)
Auto arrange the new diagram

Do a couple of simple moves on new diagram. 
Save all
Delete entire (new) diagram.
Click the undo button. It will show actions for the new diagram.

I see similar problem on Mac OS X as well.

currently workbench has one global undo stack. we cant change that for 5.2 anymore, but we will try to improve that in a later version
