What is your Shotcut version (see Help > About Shotcut)?
Shotcut Version 23.11.29
Can you repeat the problem? If so, what are the steps?
The time slider used to move no matter where you click in the track in all previous versions.
But now it just moves when you click in the dark bar that shows the timestamps.
Restarting Shotcut doesn’t help and the problem occurs in all my projects and also when reinstalling shotcut.
