EER Diagram - Tables stuck (4 replies)

Hi everyone!

I use this Workbench: 6.08.11354 build 833 Community Edition.

I made an EER Diagram with the Model Tool and somehow (after it worked fine at first), all my Tables are now stuck at the top of the window.
It is still possible to alter the property "Top" manually, but i cant drag & drop the tables below x=0. (dragging from left to right works, though)

I searched quite a bit to find an option that i unintentionally turned on(off?) but couldn't find any so far.

Please help :-)

Greetings

Stefan
