Quote:This is not acceptable, because while I can edit and alter images all I like (by first opening them in GIMP via Windows Explorer, thus bypassing the broken "File" menu), I can't save any of my work!
Not acceptable ? No use complaining here, no Gimp developers visit. The place for bug reports is https://gitlab.gnome.org/GNOME/gimp/-/issues
However, some things to try. Reinstalling Gimp over itself rarely does any good. I find even uninstalling first, leaves some remains. Un-install, close and re-open Windows and the folder C:\Program Files\GIMP 2 will now delete.
Then the version, There are bug fixes to the Windows 2.10.24 installer, it is up to #3 https://download.gimp.org/mirror/pub/gim...etup-3.exe
Installing does not remove the User profile C:\Users\"yourname"\AppData\Roaming\GIMP\ which is often contains the problem. Disable that by re-naming to
C:\Users\"yourname"\AppData\Roaming\GIMP-backup Start up Gimp and see if it makes any difference.
Always difficult with Windows, MS updates without notice so do AV applications. Who Knows ?
