Right Shift being stuck on in game

[Khatovar]

This may not be specific to ISBoxer. I use HotKeyNet and I've seen the same thing happen where basically your system gets the keydown command, but misses the keyup, thus appending the modifier to everything else after it. If it's the same thing, you should just be able to hit right shift+whatever and it will get the keyup command.

This seems more likely to happen if window focus is changing, but it's been a long time since I've actually seen this behavior. I've seen complaints of it happening a lot to people using Intellipoint {Microsoft} or Setpoint {Logitech} mouse or keyboard software. It could simply be a matter of updating that software or using an alternative driver. I can't confirm, though, because I don't remember what mouse and keyboard I was using at the time.

But, again, I'm only guessing. I'm not that tech savvy so all I can do is speculate. It could well be that something got dorked in your ISBoxer config.
