I don't know this code at all, but isn't the goal to make sure no part of the viewport extends out past 8192 pixels? It seems to me that if the globalRect.x was -1000 and width was 500, this change would set globalRect.x = 0 and thus set the viewport to 500 visible pixels. IOW, by setting globalRect.x, you are moving the left edge of the viewport to either the right edge of the stage or the left edge of the stage. Moving it to the left edge of the viewport to the left edge of the stage results in visible pixels. Did you intend to move the right edge of the viewport to the left edge of the stage when the StageText is off-screen to the left? Of course, I could be wrong again... -Alex
