If you have a separate graphics cards, make sure it is actually used by TBC:

Are you using a docking station? If you do then try and see if it happens if you unplug that one.

Which graphics mode are you using?
Go to the Support Tab -> Options and change it, you'll need to restart TBC

especially for point clouds Trimble advises to use OpenGL anyway, and I had troubles with DirectX before

TBC 5.81 freezes randomly. Doesn't matter what size file or what work I am doing. If I click on an object it will highlight it for a second and then goes away.
My curser will not show up on any of the plan views.
I can still select from the ribbon, view manager, and project manager.
I have to restart TBC at least every 10 minutes.
Please help!
