Thread:VisualEditor/Feedback/Scrolling and the toolbar/reply (9)

I've tested it on another Win8-machine (ASUS VivoBook S400 14" HD touch) with different hardware than Acer W510 _but_ with a touch screen - and... the toolbox/-bar scrolled out of the screen. So my guess is that this is something that happens when the browser knows that the user can scroll the webpage with the fingers.
