Mouse missing in Media Centre!

[RsC]

Running Vista home premium (pre-installed) on Advent T9408, Core2CPU, 4300-1.80GHz, 1022mb, 32bitOp. system.

Every time I open up Windows Media Centre my mouse disappears visualy, its there somewhere in the darkness as I can shove it to the corner and highlight various parts of the screen - but I can't see it.
This is the only programme I have this problem with, the mouse is visible elswhere on every other programme, its not as if I can simply re-install the programme as Media Centre was pre-installed when I got the computer.

Any ideas - Why this is happening & how I can cure the problem?

Does it happen in full screen mode only?

Yes, when the screen is reduced the mouse appears - why does this happen?

Apparently, there is some glitch in Windows Media Center, and as always M$ is slow to fix it:

They are talking about dual monitor display, but it seems like same thing happens on regular display:

When you run Windows Media Center in full-screen mode on a dual-monitor system, only the monitor that Media Center is currently displaying on is usable. The secondary display will not redraw and you cannot use it or interact with it. This is the design for how all full-screen DirectX exclusive applications work, and unfortunately Media Center does not have any control over that. As a workaround you can change Media Center from full-screen mode to windowed mode and then resize the window as large as it can go.

Thank you for your help - At least I can now use it fully, and knowing its not a programme fault with my own unit gives me some comfort.
You've been very helpful as usual - thanks again.
