Do you see the same behavior when somebody else logs to your machine? Any difference if you turn off/on "Enable Hardware Acceleration" toggle from 3DCONFIG? Try launching program by right-click and "Run as Administrator"?
One other thing you could try is to see if you could determine the cause. What you are experiencing looks to me like some kind of application conflict. Can you determine when the issue first occured and were there any changes to your system around that time (updates, install of some adons, upgrade, etc.).
If you ran program in diagnostic mode that would perhaps tell you if conflict is to blame. Here is how: http://knowledge.autodesk.com/support/autocad/troubleshooting/caas/sfdcarticles/sfdcarticles/Startin...
Good luck.
I don't expereince that issue on my end. It seems to me that it may be related to drivers. You may try upgrading your graphic and mouse drivers or rolling them back. Sometimes that helps.
Not sure if this is what you are referring. I can run Zoom>Extent and the command line is blank since the command is completed and I can type new command without touching the mouse. See video:

When you mentioned Civil 3D is freezing it sounded that program hangs. Am I wrong and the program in fact cannot accept commands?
I was just typing commands in the command line (not using paste). I was also able to copy, zoom>extent and paste with no problem. See:

2 posts ago your cmd was blank as well. In your last vid it is not after zoom extend. Did you touch your mouse a tiny bit? It's the only way to unblank the cmd line and make ctrl+v work and right now I get the feeling you're trying to trick me...
