Since I've been trying to beat all difficulties and subdivision of the Half-Truncated Truncated Icosahredon, I have had to do many attempts to beat some of them.
Just now I beat it on Insane difficulty, subdivision 4.
I had been trying to do that for almost 2 months now, getting within a few mines ...

I wouldn't mind doing that, if it can help find the cause of this.
I've been trying to find out other way to trigger it, besides just spamming rightclick and moving my cursor around.
I have found a way to produce the problem with a single mouseclick everytime, here's a video: https://www.youtube.com ...

I think it is more likely to happen if I click on tiles that are on the "edge" of the board.

It's an Asus.
Intel i7
Nvidia GeForce 940M 2GB

I bought it about 5 months ago cause my previous laptop died.

I am having this problem aswell.
Here's a short video showing it: https://www.youtube.com/watch?v=HjbkFV4g8-E
In XSplit (livestreaming/recording software) the cursor turns black whenever any mouse button is pressed.

I am running MineSweeper3D version 2.8.1 on a Windows 8.1 64bit laptop.
