I think stuckincincy is a mouse salesman ... lol Seriously, sometimes mice are programmed to respond differently to different apps.
Try this ... open the app(s) that you're are opening off screen ... "Alt-Tab" to select it, "Alt", "Enter", "Left Arrow", "M", then use your arrow keys to move the window to where you can see it, then hit "Enter". Close the app and re-open and it should open where you moved it to.
