I have identifiate a bug with hud ! I try to explain exactly whats happend :
see the image : bug HM.jpg
Each time if you don't put the button to reduce the window of winamax, the hud stay on screen over the other softwares like firefox, paint, outlook... Only if you reduce the poker room windows, the hud descend with the window !
It's not very bad with one window because we can reduce it easly ; but it's very bad with multitabling !
I hope that you understand and can reproduce the bug on your computer to fix it.
