[Ghost Recon freezes--A LOT!]

My Ghost Recon keeps freezing on me. At times it is random (more often than not, right in the middle of play). Very often it comes when I hit the Esc key. I have installed patches 1.3 and 1.4, but still freezes.

A lot.

I rarely get through a mission without at least one freeze.

Any help?

Alright, so just call me the village idiot.

I do NOT have Desert Siege--I have Island Thunder.

Sorry for the confusion!

O.K., I'm the guy in question, so I thought I'd chime in here.

Points of clarification:

I do have Desert Siege, have it installed, can play it, and even finished it before I reinstalled. Reinstall included uninstalling DS and GR, installing GR and DS, and patches 1.3 and 1.4. I have no other instal of GR on my computer.

Any help would be greatly appreciated!
