I'm trying to play CS on my IBM T40 laptop, but I'm having some problems with my controls..
My keyboard controls stick.
For example, if I tap the left key, it'll move hard left, as if I held the key for a couple of seconds. As well, sometimes the controls are a little sluggish to respond.. the corresponding action occurs a second after I press the key.

My second issue is with my mouse. My mouse stops detecting movements when I'm playing.. it only works at maybe 30-40% of its ability. So I'm getting shot at, and the whole time, I'm trying to move my crosshair over, but the mouse won't respond. Other times, the mouse jumps (but I can deal with that, it only happens occasionally). The mouse is a Logitech Wheelmouse, by the way.

I crossposted this in Tilted Computers.
Any help would be appreciated.

Note: I just tried again.. my mouse only lags when I'm pressing keys on my keyboard while I'm moving the mouse around.
