Wrong resizing of dual graphics views by moving the horizontal separating bar in fullscreen mode
I really like the online fullscreen mode which can be activated by clicking the little fullscreen symbol in the lower right corner. In some of my applets I use the wonderful dual graphics abilities of Geogebra, the "Graphics" view and the "Graphics 2" view. Usually I place "Graphics 2" view above the "Graphics" view.
Just like in desktop mode of Geogebra classic 5 there is a horizontal separating bar between both graphics views in the online fullscreen mode. Using the mouse this separating bar can be moved up and down to resize both graphics views.
Problem: In fullscreen mode of the Geogebra applet online in a browser, at the moment when I click on the separating bar and start moving the mouse pointer, the bar jumps to a much lower position. I still can move it up and down by moving the mouse, but not at the same height of the mouse pointer, and not at the same scaling. Is it a problem of my settings (graphic card, monitor, browser, etc.) or is it a known problem?
