Mac OS X 10.7.4
Brand New Microsoft Natural Ergonomic Keyboard 4000 with the latest software.
Game is fully patched.
This has been an ongoing issue for some time, but it's REALLY gotten bad since launch.
I'll be playing and especially when I strafe, whether I strafe in a straight line or strafe radially, it is not now uncommon for me to get stuck.
Worse, logging out does NOT fix the problem as I will log back in STILL stuck strafing. I've deleted cache and removed WTF folders, etc.
No clue what else to do. Guildies report no issues like this on the PC side.
