I am using the Keyboard Layout Creator (MSKLC) Windows 11 and I am trying to create a Keyboard Layout with Swiss German Caps and Dead Keys. So e.g. the key a, in SGCAPS, will switch to a dead ^.

This works great when testing in the build in test window of MSKLC, but when I install the keyboard layout to windows and use it, the ^ will be there on SGCAPS but will not work as dead, but as a normal key.

Anybody has any experience with this? Is there a way to fix this?

Kind regards
Bastian
