I have two displays (two monitors) connected to my machine, and I noticed a strange thing happening today. I had an Explorer window open with my compiled exe on my primary display, and when I double-clicked it, it opened in the primary display (left monitor). However if I pressed enter to launch the executable, it started in the secondary display (right monitor). The window state of the initial form is maximized. Is there a way to tell C# to open the initial form in the primary display?
