Qtdragon interface touchscreen no longer responds during operation.

Hello,

Another problem just now.
BS and Linuxcnc up to date.
I wanted to quickly plan a small area using the Qtdragon jog button.
But for reasons that are not clear, the interface no longer responds to touch inputs, the machine continues to move to the limit switch, the button remains selected even without touching it. The touchscreen still works in the system, but Qtdragon is not accepting anything. Keyboard inputs are still processed and selecting with the mouse also works, and changes are also displayed in the interface.
That could have ended badly.

I'm slowly getting embarrassed, especially since I haven't changed anything except for adjusting the postprocessor for myself.

Best wishes and thanks in advance, Frank.
