Installed Tiles on XPP SP3 & ran it in one profile (local machine). Played with it for awhile, trying out each Tile Panel size and various other settings, then exited the program.
Now, even after a reboot, maximized windows are limited in width as if the large Tile Panel were there; won't max to the right screen edge (or to right-sided vertical Taskbar), leaving a big gap of wallpaper. How do I get windows to max properly now?
EDIT: With apologies: I discovered that Tiles was loading on startup 'underneath' my vertical Taskbar & unseen. Even so, windows were not maxing to the edge of the Tiles Panel (small size) or Taskbar with Tiles running. I exited Tiles again & windows now maximize properly.
