Thank you for your answer.
I already use this programm on an old computer, so a know all the chek box possibilities. I have already tried what you said but no result.
Before purchasing a new license (for my new PC), I'm usinig a trial version. Is it possible that when it's registred, the software is updated? Or even for the trial version, I have the very last version?
Is it possible that a win 8 + screen 1920x1080 makes it "out of range" the the mouse to be detected when it's over on the edge of the screen?
NOTE : If I have the windows exploror on screen ==> it works just well (pop-up normal with mousse on edge). But when I have for example FireFox ==> no way
I CANNOT think of using a computer without objecdock so if you have any other idea, I will enjoy to try it.
