System: TinyCorePure64 V 12.0
Environment: out of box, nothing added
Noticed a bug - well more of a quirk.
Normally when I have a terminal or other application open, and I want to immediately go full screen, I'll use the keyboard shortcut of CTRL-ALT-M to toggle it.
BUT - I did something nobody else would do:
With no application open at all, I did a CTRL-ALT-M just to see what would happen.
Nothing immediate. But I did notice that I lost the ability to bring up the hierarchical menu on the desktop. In addition, when activating any applications, the fvwm handles to grab and move them around were gone too.
Solution: The simplest was to use the gui exit manager, logout, logout at the command-line, log back in and everything was back to normal.
Alternate solution: Don't be a weirdo testing CTRL-ALT-M when there are no applications active on the desktop.
So just a quirk really. Not a showstopper. I haven't tested this with any other *cores yet.
