Arbitrary Cursor Movement

Is there some way to control the random cursor movements that occur in the sql editor? I'll be typing and suddenly my cursor jumps to some other place in the doc and I have to move it back to continue.

Do you think you could make a video of the case? I don't think I've seen it happen consistently in Toad.

I would be willing to give it a shot if that will help. I'll probably need to record while I work and edit it down once it occurs. I think I have Camtasia installed.
