Crash on moving a unit

[tankorsmash]

I don't know exactly what I was doing when it crashed, but I was definitely pressing some combination of A, Shift, Ctrl and Caps Lock along with clicking when it happened. I was trying to get a unit to move. I thought I clicked on a unit but may have clicked off the map.

I don't know exactly what sort of info you need, so let me know. I was playing on Windows 10, using the Origin RA2 files.
