Mine does what Rusty's does. However, it doesn't seem to interfere with any key passing. I have have many keybinds tied to alt, but haven't noticed any conflicts. There might be a way to turn it off in the options menu. I'm at work now so I'll see what I can figure out when I get home.
Maybe it's my imagination, but I'm convinced that sometimes bindings passed from ISBoxer don't function on my Slave toon due to the FTL modifiers interfering with Carbonite. I'll keep an eye on it and report back if I find anything. (Incidentally, assigning all the keystroke options under "map" in Carbonite to none doesn't seem to help.)
