I have this problem: the relationship graph redraws every operation i do on it. When i move a table, when i add a relation... it's impossible working! It's a knowing problem? How i solve it?

Please help (and sorry for my english).

The obvious suggestion is to update your video driver/ software.

If you are using a Nvidia graphics card, try updating your ForceWare software...

I've read somewhere once before that this solved the same issue for someone else.

Make sure you download the appropriate updates for your particular computer setup.

Also get the latest DirectX updates for your system...

I hope this resolves your issue!

Try turning down the graphic acceleration level.

If you're on Windows, the problem is because you have some folders minimized on your toolbar. Close all those and the problem will go away. And pressure FileMaker to fix this while you're at it.
