When I play EQ with WinEQ2 I can move the mouse over to my primary monitor and use it there to click websites etc. when I move my mouse back to the secondary monitor and click there the character goes into mouselook mode and I will have to click again to release it. When using IS with EQ2 this mouselook locking does not occur and when running two eq2 sessions (one on each monitor) I can swtich sessions by just moving the mouse to the other monitor and clicking there.
When I play WoW (started last weekend

Now obviously I prefer the IS behaviour with EQ2 and the WinEQ2 behaviour with WoW. Is there any reason for this different behaviour and more importantly can I change any setting to make this work 'correct' all the time?
Thanks,
