One thing is very fustrating and/or confusing with Ubuntu is the lack of the fact that when you double clic to open a folder, or any icon on the desktop, the mouse icon is staying the same (not like on Windows) so sometimes you feel like you didn't correctly double clic.

So you double clic again and again until you see Ubuntu responding and opening ten thousand folders.

I am not found of Ubuntu because of this little bugs, I've been testing since Ubuntu 9 and we are in 2013 those anoying bugs are still here.

How to contact the devellopers for this old bugs to finally be eradicated ?
