I have a Medion 86635, it's an old tablet, and the right click and middle click buttons that I have on the pen don't seem to want to function like the mouse. For example, the VAB, I can't rotate the view, but I can pick and place parts, as well as open the right click menu and change things such as fuel levels and thrust limits. Once launched, I am able to right click parts, and change things much like in the VAB, however I am still unable to rotate the view. As a test, I right clicked with my mouse, and moved with the pen, however I was still unable to rotate the view. I use it all the time, and for programs like Photoshop, it right clicks just fine, infact it works for games, like Interplanetary, Banished, and Harvest: Massive Encounter. Is this a problem with KSP or my tablet/computer? I would REALLY like to use my tablet to design ships, because it just seems cooler, and I find it easier to use than a mouse (my opinion and experience).
