PROSTEELWERKZEUG_S6 - Tools - problem

Helo All,

During using "PROSTEELWERKZEUG_S6" tools for prosstel I have faced folowing problem.

Tools called "Bearbeitung" does not work properly, folding menu, shown below does not appear.

I have tried to change diameter of existing drillholes, unfortunatelly failed.

What may be a reason of that behaviour?

J.
