I can quit anytime I want! I just don't want to yet.
BTW, if you miss live chat, you should go and make the IRC teachat room lively. #teachat on Rizon.
I am on a laptop, and the mouse is a square pad below the keyboard. My cursor has "floated" off the screen. It is impossible to get it back using the square pad. I can force it back onto the screen using the purple ball above the "b" key, but it is a major struggle! How can I get my cursor back?
That "ball" is also the mouse. You have two ways to work. Personally, I prefer the trackpoint (as IBM calls it), but to each their own (I've gotten adept at the pad since my Toshiba model doesn't have the point).
The thing is, that thing is (usually) a strain gauge. Basically, it measures the force put on it to determine how far and how much to move the pointer. However, it often needs to recalibrate as temperature changes and as you use it.
In your case, it looks like the thing gets stuck in one direction and forces the pointer to the side. Not a common problem, but it does happen.
One way I've found that often works is to move your finger on it in a circular motion a few times, reversing the direction about halfway through. Apply a decent amount of force, but not when doing this. This usually causes it to fix itself.
If it keeps having an issue, see if there is a setting in the computer to disable the pointer. Usually, when powering on the system, you'll see a keypress for going into "setup". The setting should be in there.
