Alt+W

[בן של מלך]

There are marks in Hebrew that can be written only by pressing alt W.
The problem starts when I want to write while editing OpenType that I cannot add this mark, because when I press alt W, the window closes, without the changes.
What happens is that I lose a lot of important work from the habit of pressing alt W.
My question is if it can be fixed, it's not a bug but it's really annoying.

Alt+W is not used in FontCreator. Ctrl+W closes the OpenType Editor window without warning if no changes have been made. If any changes have been made, a warning dialog will be shown.

Alt gr + W close the window, check.

Alt gr + W close the window, check.

AltGr is not equal to Alt.
AltGr+W does not close a font like Ctrl+W does, so this may be a bug.

You can call it a bug, for me it closes the window and undoes everything I've done.

Alt gr + W close the window, check.

It does not close it here on my machine. Can't fix it if I can't replicate it.

If there are changes, a confirm dialog is shown. It contains a "Don't show this warning again" option. It seems you once checked it, so you no longer see the warning dialog... You can revert it through the Options dialog.
