Suddenly Enable Time Delay freezes MadCap Capture

[DocuWil]

I hope someone can help.
When the option Enable Time Delay is not set everything works fine.
However, normally I always (some years already) work with this option and never had any problem.

Since today this option freezes MadCap Capture and I have to kill the program.
I have tried everything: restarting Capture, restarting my PC, repairing Capture, re-installing Capture completely, closed Flare.
Nothing helps.

As I need the option very badly I am now forced to use Snagit
