Mouse cursor/screensaver problem

Hey I have a slight problem and noticed this a few months ago on my iMac G5 (10.4.4) but I've never really asked anyone about it until now - the problem is that whenever the computer enters the screen saver, the mouse cursor is still visible, (the cursor doesn't disappear), and in the same place that it was when the screen saver wasn't on yet. This is just a slight annoyance, but it's probably some easy fix that I didn't think of yet.

Thanks!
