hummm... are you a gear swapper? I know that if i'm swappin stuff and getting cast on or casting on someone, sometimes I'll "spell lock" er w/e and no animation so I'll sit there and bang on my macro to make sure I'm actually doing what I want to be , I attribute it to lag and this game just being ancient. I run on a similar system, and it .. happens. especciallly around flux's or tele points. (not so much around recall crystals though)
