Can't drag regions with the mouse anymore

Hello

I have recorded a couple of songs. A went quite well. But suddenly I can’t drag the recorded regions with the mouse anymore. I still can resize this regions but not move.
All other songs are behaving normal.
Any idea what I’ve done wrong?

Sound like you have changed the edit mode from “slide edit” to “splice edit” or “lock edit”. Check the option right beside the tools.

That was it.
Thank you!
