XnView Software

XnViewMP 1.7.0 64bit
Windows11 (23H2), display resolution 3840x2160, win scaling 150%

Viewer/Browser - shortcuts
reassigning requires tab reopen

To reproduce:
1. open any image in Viewer
2. goto Settings>Interface>Shortcuts
- reassign any shortcut for Viewer, eg '/' from 'Fit image to window, large only' to 'Fit image to window'
- press OK
3. press /
nothing happens, menu shows key assigned to old and new command
it's fixed only after tab reopen, same issue with Browser tab shortcuts

Thanks to your detailed description I can reproduce the problem.

This problem is supposed to be fixed in XnView MP 1.7.2. Please check and confirm the bug fix here.
