Description

After setting the brightnes with the xfce4-brightness-plugin 1.2.0, the recognition of the first mousebutton is disabled for some elements of the xfce-panel, when using a N-Trig Multitouch device. The are some ways to get it back with a keyboard, but the problem is quite nasty, because the device is unusable without the first mousebutton recognition. It is a general problem of xfce-panel, because the same happens with the volume control.

System: Fujitsu Q550
