Hello Tom,   I'm sorry that this issue causes some inconvenience to you. There is a problem with the visibility drop-down menu in the layer/class palette when the floating pane is active. We are addressing this issue now and hopefully, the fix can be push to the public sooner or later. Before that, you may need to click on the empty area on the palette to notify the palette to be activated before clicking on the drop down. The floating pane will still be active unle
