How to repeat:
try to create a relation between to tables

We would need some more info on that issue please:
- Is the problem persistent or did it just happened occasionally?  
- Are you connecting columns on the diagram using your mouse or setting up the FKs manually in the table editor?
- What version of Workbench are you using? (most recent would be 5.2.16 currently)
thanks in advance

I am not using 5.2.16, but the problem persists each time i use the FK table editor

What exact version of WB do you use? If it is NOT 5.2.16, please, upgrade and check if the problem is repeatable.

Hi, the version is 5.2.16 and the problem does repeat.

Yanis, are you experiencing that problem while working on an EER document or when working with live DB objects in SQL Query Mode?

It happens when i work on an EER document

Which operation system version do you use?
