Hello,
I have done some test in laptops with resolution 1366 x 768 and when you open the program, the header of the window is not visible, there are 2 "tricks" you can do to solve but i think that's not the solution, you can change the resolution once the program is opened and back to the original again, and the window header appears, and the other is moving one of the sides of the window...
The threshold doesn´t apear, still working, but doesn´t show the debug image.
oh, and one last thing, last installation step --> "create desktop icon", icon is not created.
I have test this things under OS Windows XP and Windows 7, with same results.
Thanks!
