I get that sometimes too for no reason. It's normally when I come back after not playing for a few months and Im a bit lost again.

It seems to always just solve itself for no reason that I can find out.

Just keep fiddling around with things... test if the command works when no keyclone is running, trying reinstalling G-Series Profiler, try messing with the keybindings a little, test the key in NotePad to make sure it's not the key/g-series program

( my problem was I had spells that SHIFT would make them cast on target A, and no mod would cast it on themselves. Well everyone would be casting on a different guy >.< )

I know EXACTLY what you're talking about, but I never found out a solid solution myself, it just seems like 20-30min of tinkering always fixed it haha.
