I've only used SnagIt 13 on my Microsoft Surface Book for a few minutes, but noticed it's having problems with drivers and extended desktops. I occasionally get messages like "Display driver has stopped responding..." at which point I need to reboot my computer for SnagIt to work again. And I can't use the SnagIt editor on my extended screen. The scaling of the application gets huge and exceeds the screen boundaries. On the bright side, v13 solves the problem I had with the previous version where the toolbar options appeared minuscule on the Surface Book screen.
