Sorry to hear that. I spent a while trying to get the app to show extra windows, but it worked properly each time.
The simplest thing would be to reset the app’s defaults for window position. You can do that in the Terminal.
- Quit Nitro
- Open Terminal
- Enter the following command, INCLUDING the quotation marks: defaults delete com.gentlemencoders.nitro “PersistentWindowState v2”
- Open Nitro
If this does not work, then execute this simpler command to reset all the defaults (quit Nitro first).
defaults delete com.gentlemencoders.nitro
