Question

I have an HP Pavilion dv5224 laptop. pe I find that when I ty at a clip, things like what just happened (my cursor somehow jumps to another place in the para--from ty to 1st line pe). This happens pretty frequently, and usually when I'm typing fast--not slow. It is very annoying. I can't figure out why it does this. I am not inadvertently hitting any of the arrow keys--they are far down on the right. It might be related to the space bar, however.
