Hey I love this screensaver!
I have just one problem: the screensaver seems to completely ignore mouse movement once it is done fading to the set darkness level.  Once faded to the set darkness level, I can move the mouse around for an hour, and it still will not undim itself unless I click the mouse or press a key.  The mouse cursor hides when fading begins, and will never show up again once if it is at the set darkness level, unless clicked or key is pressed.

If I move the mouse while the screen is fading however, I have no problem, and the screen returns to normal.

My settings:
Start of Day: 7:00
Darkness:255 (however, any darkness setting returns the same problem)
Start of Night:22:00
Darkness:255
Darken Speed:
Steps:255
Delay:0
Lighten Speed:
Steps:25
Delay:0
Actions that quit dimsaver:
Mouse Moves: Checked
Mouse Clicks: Checked
Keys: Checked
Mouse movement time before quiting:
50ms
I have no image or screensaver configured to load.

P.S. My XP install is only 1 day old, so I doubt I have any programs conflicting with the DimSaver. I only have 1 aditional app running in the background: Microsoft OneCare.

Edit: I have concluded that this only happens when no screensaver is selected to run.
