Invisible Mouse Pointer

I picked up a used NEC MP900 which was flash update to CE 4.2. I've been lusting for one since I saw a big V.P. at my workplace using one.
I've plugged in a wired mouse into the USB port, but I really can't see the pointer showing up on the screen.
I have to right click to make the menu pop-up to determine it's location.
Is there a software program to make it more visible?

Is this one upgraded with the Cmonex 2.0 ROM, by any chance?

scotterbug, please provide the information from the nec firmware info.

If you are not using P530_42 2.02 with bootloader 4.10 head to HPC:Update in support and update the rom to the latest version.

If it is using a hacked rom then you need to look for the latest version of that release or flash back to an official version.

HOWEVER you MUST ensure that your bootloader is 4.10.

Yes it is using the Cmonex 2.0 ROM upgrade.
