thanks for the help, guys. i actualy gave away a razer boomslang i won at a lan party less than 6 months ago. i can get it back, since the person who has it uses something else (don't know why). the good news is, i took apart my ifeel mouseman, cleaned out the dust bunnies that were collecting around the lens with a blast of compressed air, and put it back together and it works nicely again.
i don't think i can go back to a "normal" mouse again. i like the force feedback, and i don't understand why more companies didn't jump onto the bandwagon. i might stockpile as many tactile mice i can find in the near future for when this one goes.
