Display Freezes Unless Mouse is Kept Moving

When I have a display on the screen that has a an incrementing item on it such as a clock or a counter of some sort. I've noticed that the display stops updating unless the mouse is constantly jiggled.
The computer does not freeze up nor is any work lost. It's just that the screen does not keep the count updated.
When I jiggle the mouse the screen will update to the latest count but when I stop moving the mouse the screen will hibernate again after a couple of seconds.
Not a major problem but very annoying.
I also had this problem with Mandriva and obviously it has carried through to Mageia. It is not computer dependant this happens on every installation I've done irrespective of the hardware involved
Does anyone know how to fix it ?
