Keyboard on Master stops working for anything but commands?

I am running Windows XP with a standard keyboard. Using 2 monitors to run 2 instances of WoW.

Problem: After a seemingly random amount of time my Master client will only accept commands for mouse clicks. I can't type anything. (no / commands etc)
My other instance of WoW works just fine for typing etc.


The only way to restore typing functionality to my main client is to restart wow completely.


Any ideas?

Thanks in advance!

should be fixed next build. This rarely occured for me, but it occured to me what might be happening here. Sometimes mods can get stuck (ie after alt tab) too.
