Since the last patch on retail 9.15 the addon no longer allows long combination for a direct key binding is Ctrl+Alt+M in my case, shortens it to Ctrl+M.

Revert to the previous version of the addon and Crtl+Alt+M works fine.

I tried this and I don't have any issues setting a long keybind (ALT-CTRL-L).

Can you be more specific about what you're doing any what's happening?

Closing this off, I'm 99.9% sure it's not a LiteMount issue. Please re-open it if you have more information.

Any info? Will close this soon unless I hear back. If that happens feel free to re-open it if you still have a problem.

HI sorry for the late reply. Ctrl+Alt+L works for me but Ctrl+Alt+M still doesn't, why I don't know. Have you tried Crtl+Alt+M?
is it a protected short cut?

I didn't have any trouble with that either. Perhaps it's something in your OS or maybe even your keyboard.
