Description:
When you try to add a new 1:n relation (maybe it applies to other kind of relations too) during save, the program hangs.

How to repeat:
1. Take a slow machine
2. Create a complex model, so saving it will require at least some seconds
4. Create an ERR diagram and go to it
5. Modify a table as you like, an asterisk on the title bar now indicates that they are pending modifies to be saved.
6. Click the "save" button
7. Click the "Place new 1:n non identifying relation button" and then click a table before the asterisk in the title bar has disappeared
8. Workbench is now stuck.

Suggested fix:
No idea, the simplest fix should be disabling all buttons until save is completed.

Thank you for a problem report. Please, try to repeat with a newer version, 5.0.29. In case of the same problem, please, upload some complex model that gives you a hang.

I've just checked, I can confirm this for 5.0.29 too.
I'm sorry but I didn't obtained permission from the owner of uploading the very large model I'm using to reproduce this bug.

Anyway, it should happen with any model, the large model is required only to increase required time for save and letting you push the relation button before save is completed.

Testing it on a slow machine (or maybe an intentionally slowed down virtual machine) should sort the same effect.

If your hardware reach this minimum of hardware requirements.

My hardware doesn't meets minimum requirements (it lacks OpenGL 1.5 support), however, staying to what it's said, I should experience only performance slowdowns instead of software hangs/crashes.

Thank you for the feedback. Could you please install OpenGL 1.5 and try again.
