FlashPrint Opens Off-Screen

If you open FlashPrint and the app appears in your taskbar but not as a window on the screen, it might be due to your monitor setup. The app records what the last window position is and places it back there. If you have a multiple monitor setup and open the app later without a screen you might have a massively negative number on your windowRect property.

To fix this, just edit the config file

C:\Users\<username>\.FlashPrint-MP\config

[history]windowRect=@Rect(-3249 53 1078 1157)

to

[history]windowRect=@Rect(0 53 1078 1157)
