Hi Alex,
Try using the Windows+Left, Windows+Right keys to re-position the window. Whatever windows has focus can be moved around this way. You will have to find a way to ensure the Spike window has focus, you could probably select it with the alt-tab method.
Or… Check this link out as well, I think this applies to you

If these do not work, read on, otherwise ignore the rest of this message.
What I think this comes down to, is that Spike remembers where it was last placed, and with your multi-monitor setup it is re-opening in a place that no longer exists or is off screen. You can force Spike to re-open in the middle again with a small amount of work.
Navigate to this directory
C:/Users/YourName/AppData/Roaming/SignalHound/
AppData is a hidden folder, you will need to show hidden folders.
In this folder you should see a file called Layout.ini, you can either delete this file, or edit it in notepad and remove all the info under the [MainWindow] and save the file. The Geometry value is what is storing your window size and location. Launching the application with that deleted should restore the defaults which is centered and full screen on the main display. (If the other screen is still what Windows considers the main display, it will probably still open on the other window).
Regards,
A.J.
