When I edit a test, and will configure an existing schedule, a popup with the following error appears:
"Cannot focus a disabled or invisible window"
When I edit the schedule via menu profiles, there is no problem.
I seems this happens only the first time after starting HM.
Could you please send your configuration files to our address line1@ks-soft.net?
I need your files because I tried versions 3.10-3.13 and cannot reproduce this error.
