[Lxqt] Problem with Network Widget

Hi, I see a problem with the network widget on current TW: Right-click on the network symbol to select a new network. The widndow opens, after 2 secondes it flickers 2-3 times and closes again. No time to select a network!. Hitting 'N' keeps the windows open in most, but not in all cases. Anyone else sees this issue? Cheers Axel
