Have you any ideas?

thank you for reporting that issue. We will try installing the same version of MySQL Workbench and try reproducing it.

This issue appears to be specific to MySQL Workbench 6.3.9 64-bit that introduced some backward incompatible changes. We will have an update for that available in SQL Assistant version 9.2 expected couple of weeks from now.
