Hi everyone, hi benpaddlejones, I got a question for you again

I have tried to use wiimote whiteboard with 2 Chinese whiteboard softwares I found online, they are generic whiteboard softwares, which means they are supposed to work with any generic whiteboard, as opposed to the software provided by interactive whiteboard manufacturers which work with their own hardware only.
The 2 whiteboard software I've tried work with mouse without any problem, but they just don't work with my wiimote whiteboard, the cursor of my IR pen disappears as soon as it comes inside the area of the software, and the click or movement do not function at all, but when I use the mouse to move the cursor out of the area, the IR pen starts to work again.
The 2 software I have found both need to pay for, what I got is the demo version, but I don't think that has anything to do with the problem.
It seems the wiimote whiteboard conflicts with other commercial whiteboard software? does anyone have experience on this?
I want to call the support team of the software tomorrow but I don't know what technical questions they would ask and how to answer that, I am not a programmer, and I think they have never heard of wiimote whiteboard, could anyone tell me what they would need to know about wiimote whiteboard so they could help me fix this?
Thanks!
