The osciloscope freez after zooming horizontal domain with displayed cursors.

1. I have input signal on Chanel 1
2. Set the cursors A and B in mode Track
3. Zoom the horizontal axis by clicking Sec/Div button
4. Change the time(horizontal) range to zoom more, cursors are not in window (out of display on zoomed part)
5. Click to clicking Sec/Div button, try to exit
6. The display is frozen and device doesn't response

I have DSO2D10 with SW 20220105, same with 20211230

Thanks for FW dso3kb_20220124.upk, i can confirm that fixing the freezing when user exiting from zoom mode.
The remaining problem is cursor malfunction in zoomed window when cursors go out of zoomed area during zoom in 3x or more. The cursors are moving in main signal, but are stuck on left edge of zoomed signal and don't move.
