Ah OK, thank a lot.

IC.

The good news: I can confirm that you can rotate menus in Cuis.
This should give me a clue to make my buttons work.

The bad news: By (bad) luck, I found a way to create
Menus that do not scale or rotate:
Start a fresh image,
pin the world- and the preferences-menu,
change the system font to a true-type font,
rotate one of the pinned menus.
Watch the shit hitting the fan.

Any chance to recreate the menus with the proper font?

Admittedly I learned to like this (mis)feature.
Often I create the menus with a bigger font than I will use for
windows, especially when my eyesight is bad due to hay-fever.

Yes ok.


HTH,
