Comment 6 for bug 1751482

I use latenight theme just default, and tried other themes, same result.

I dont use any theme application like rainmaker, and all my visual effects are off, except smoothing font edges. I can use other application very well, like ableton live, and ten's other application.
Mixxx 2.0 worked fine. before installing 2.1

My windows 7,32 theme is just plain black, without any effects.

Yes its odd, an there are at least one other person in bug report who experience same. and saw in forum.

I have tried to figure out what is it, but no bright light in bulb.
I have experience of programming long time, and fighting with comps. I mean not just typical end user.
whose mouse is doing tricks,

I havent chaned system colours, it just dont activate the row and highlight it, and change active track, it activate tracks and highlights them if i am pressing arrow keys.
and it load track to deck if i double click.

I am using just standard logitech plain simple mouse, which is not special game mouse or...
