Update to version 1.0.0 Preview-4 Simplified the "Boot Atari Executable" dialog by removing the "Keep this dialog open" check box. The dialog will now remain open until it is exclusively closed by the Cancel and Close buttons. This update also fixes the issue of opening multiple instances of the said dialog. The issue was not immediately apparent, and I found about it only after I posted the Preview-4 zip file above. All instances of the dialog was opening at the same exact location of the screen and only the last dialog was visible unless the dialog window is moved, revealing the previous one hidden underneath.
