Have a weird issue in XnView in Linux Mint (maybe in Win11 too IDK)
Alt-M pops up the Move dialog.
I expect to be able to do Alt-M. Move a file. Then Alt-M again, to move the next file in the file list.
This works inconsistently, it's like the file list window _sometimes_ loses the focus and the Alt-M does not work anymore. I have to click on the filename for Alt-M to work again.
I've removed (I think) all OS level shortcuts that use the Alt-M key combination.
