Hmmm, none of the above unfortunately. Whilst I did find the forced window option, I followed recommendations (or negative recommendations) and left it deselected. Hardware cursor is definitely selected in Wow.

Two strange things. WoW launched outside of IS seems to be immune to the problem. My laptop on which I previously boxed using Zanthor's original IS setup without ISboxer is immune to the problem.

I'll try and catch you on irc in the next couple of days if possible Lax.

Cheers
