Graphics problems when using Torque

After a while of being in the TorqueDemo or even a tutorial which I do in Torque, the graphics on my entire laptop is messed up with green lines/boxes all over the place. Initially, they occur in just the Torque window but after that, it starts showing up in the title bar of other windows and then finally inside all windows until and is there until I reboot. I've checked that my video driver is up to date. I have the FireGL board. It happens whether I have selected OpenGL or D3D as my TGE display. I use this laptop for game development in other engines and also for playing/testing 3D games.

Is this a known problem which requires me to do something? Any ideas?
