How to repeat:
have a table definition in the upper right hand corner of the page. Another table placed elsewhere on the page. Select the relationship button for existing fields (last one on the list). The help box will cover the table definition in the upper right hand corner, however you can get the field to highlight if you place the cursor carefully, when you click WorkBench crashes.

The problem actually appears to be related to a type mismatch between the parent and child fields. Of course with the help box overlaying the table definition I thought that I was picking the PK when in reality I was picking a VARCHAR field. Either way something other than a crash message would be nice. The error did not actually close the WorkBench so I was able to save my work. Hope this update helps.
