So you are trying to send ! from window 1 to window 2? (Shift-1)

I don't know how KeyClone is handling shift states, I don't use any in that fashion... What I do is this...

Keymap for Aazan
CTRL-ALT-1 = DMint_1
CTRL-ALT-2 = DMint_2
...
CTRL-ALT-= = DMint_Equals

Keymap for Bazan/Cazan
1 = DMint_1
2 = DMint_2
...
= = DMint_Equals

What this does is let me bind Bazan and Cazan to my normal keys, so I can flip to their windows and press normal hotkeys and it just works. It DOES send ctrl-alt-1 back to Aazan, but the only time I flip is when Aazan is dead, so it doesn't matter.

If you fire up the keymap editor and press your x-keys ! bound key, dies the "Key" field show LSHIFT+1?

Additionally are you whitelisting keys? If you are whitelisting keys make sure that the keymap combo's are on the whitelist or it wont work.

If you are cloning to a 2nd pc, load the mains keymap on the main, and the clones on the clone... I haven't been able to make the keymap work if I load them all on the master machine...
