Hi guys, I tried to find a solution by searching a lot here and on the web but I couldn't.. Here's my problem: I launch a 3DVIA Studio program on the Surface. It's not designed to work on a tablet. It's designed to work on a PC but somehow it's working quite well on it but ONLY when I have the keyboard connected to Surface. If I launch the program while the keyboard is disconnected I have a different behavior when I'm using the "zoom" feature with my 2 fingers. Indeed it's like the zoom event goes in loop and thus I'm going gorward infinitely.. Same goes for the "Unzoom" feature. Do you guys have an idea on how a missing keyboard can affect touch events ? Precision: when I launch the program, it goes automatically in fullscreen mode. Thanks in advance for your help !
