Computer freezing with Kerbal Engineer?

[Pipcard]

Recently, it seems that when I have Kerbal Engineer installed, there is a significant chance that my computer freezes/completely locks up, forcing me to cut off the power (turn off the surge protector) and reboot the computer.

It does not seem to happen when it is not installed.

It happens randomly, usually in the VAB or SPH, so there is no procedure for it to be reproducible. In the assembly building, a part is usually being highlighted with the cursor when the freeze suddenly occurs.

Can someone please explain to me what might be causing this?

It still freezes randomly, even without Kerbal Engineer.

For example, I was trying to use the new resource mining system, and when I tried to click to change the time warp, it froze.
