Ahhh, well, I've never tried to run LS on top of explorer, but I imagine that if you try to emulate explorer hotkeys with LS - hotkeys that have *already* been registered by explorer - then you'll have a problem. If you must run LS on top of explorer, then you'll want to comment out those "emulation hotkey" definitions in your hotkey.rc file.

Why are you trying to run both shells simultaneously though?
