Ctrl+A not selecting all files

A recent recurring problem whereas Ctrl+A does not select ALL files. Edit>Select All - does work correctly as before. I suggest this might relate to the recent Beta update?
Version: Pro Edition 12.7.4 x64

Thank you + Regards

Does Ctrl+A do something else?

If you go to Settings / Customize / Keys, is Ctrl+A listed? Check there's only one entry for it and that it runs the right command.

Thank you Jon...Yes there are 2 entries. I unchecked Show VIEWERCMD=selectall and it seems to have fixed my problem...

Thanks

That command is only normally active in the standalone picture viewer; if it's interfering in a normal Lister it suggests you've somehow turned on the Image Viewer toolbar in the Lister. There's no reason to do that; it's only designed to work inside the viewer and won't actually do anything useful as a normal toolbar.
