I have this annoying little problem where I'm flying along happily in FSX, zooming the view to my heart's content, and then all of a sudden I am unable to use the + and - keys to zoom in and out. I'm still able to move the camera around the aircraft and I can still use the Ctrl+ and - keys to move the view towards and away from the aircraft, but the zoom is disabled in all views, even top down. Anyone else have this issue?-Scott

Scott, this will happen occasionally whenever the screen loses the "mouse focus."Simply hit the Backspace key to regain "mouse focus," or click any empty spot on screen to regain "mouse focus"

Thank you for the tip, I'll go try it out.-Scott

If that doesn't do it try Control backspace.Dewey
