Hi Michael, thank you for your quick response.

I´ve reinstalled the Jun-12 beta beside the Jul-17 version and tweaked the history, following your instructions.
The result is a working Jun-12 beta (except the HIDE-function), but the Jul-17 beta (not your new version yet) does´t work at all. It produces the same bugs...

If you need additional informations or wan´t me to test something on my "stable" machine - let me know.
