Vista - Mouse pointer shadow problem

I have problem with mouse pointer shadow disappearing in some time... I
installed this Vista Home Premium about two weeks ago and I have had to tick
from Control Panel/Mouse/Pointers two times already that "Enable pointer
shadow"... It just sticks for a week and then disappears again, and when I
check from Control Panel option is unticked... Strange problem indeed... My
mouse is Logitech MX400 Laser Mouse and I have Logitech SetPoint latest
version installed, but I doubt that it can change anything because in that
program there is no option about pointer shadows...

My specs:
CPU: Intel Core 2 Quad Q6600, quad core CPU @ 2,4Ghz, stock cooler
MOTHERBOARD: ASUS P5K Premium, 0302 Beta BIOS
GRAPHICS CARD: Nvidia GeForce 8800GTS 640MB @ stock speeds
SOUND CARD: RealTek ADI AD1988B
RAM: 2 x 1GB DDR2 G.Skill PC6400 @ 800Mhz, 4-4-4-4-12
HARD DRIVE: 500GB Seagate ST3500630AS SATA2
CD/DVD DRIVE: Samsung SATA SH-S203B
POWER SUPPLY: Antec NeoHE 550W
OPERATING SYSTEM: Windows Vista Home Premium inc. updates
DRIVERS: ForceWare Beta v.163.71, Intel Inf v.8.4.0.1016

No other major problems with mouse or Windows...

And now it disappeared again after playing game in full screen mode... I find
this very frustrating...

Unfortunately, since that is a driver problem and you have a Logitech mouse
and program, they should be the ones you post to. They may have a user
group or you can contact tech service.

Okay didnt realize that... Thought it could have something to do with
Windows, because one can change pointer shadow options from Windows Control
Panel... But, well see, Im going to check Logitech for support.

In control panel you access the options provided by the mouse driver.
