here a screen :

if I move the mouse to up the cursor, it's actualy down on the window, and the cursor looks inverted (It's not obvious on the screenshot)
I didn't updated this project since last september. I thought a conflict between two cegui version, but I recompiled everyhting (cegui 0.8.4 stable release) on two computers after havng removed all cegui version on my system, both computers give the same result.
I'm using OSG right now, but some days ago, before I recompiled, I was still using OpenGL directly and got the same result.
the code of my gui can be found here : https://bitbucket.org/nicooplusplus/boo ... ?at=master
