DxNothing windows stange behavior on mouse over
I setup a 5 box with 1 main and 4 windows at the bottom with Video Fx layout.
It starts ok, with character 1 at the top, and characters 2-3-4-5 at the bottom.
But if I mouse over any character at the bottom (just mouse over, no action), then one character at the bottom is randomly replaced by character 1.
So character 1 shows 2 times: one time in the main window, one time at the bottom.
I have no idea what is going on. I used the default wizard for the layout and don't understand what is happening with ISBoxer.
Any help would be greatly appreciated, I have spent hours already on this.
See screenshots and xml.
Thanks
