Often while in tablet mode, for whatever reason the window I'm in will deselect, so all the controls (the finger scrolling, the page up/down buttons) won't work until I take my stylus and click inside the window again. Is anyone else having this problem? I look in my system tray to see if anything pops up that would cause the current window I'm in to become inactive, but I never see anything. It's an extremely annoying problem and I can't for the life of me figure out what would be causing the window I'm in to deselect. Any clues?
