Display discrepencies

What would be the culprit for resizing the application differently, depending on how you launch the program? For example, if I launch the program by pressing Ctrl-F5, my program is displayed normally. However, if I double-click the program through Windows Explorer, the program becomes resized to look "skinny". Also, this problem only happens when I do a Release build. Debug build seems to be okay.
