I dunno'. I stuck the mouse pointer off the top of the screen and double-clicked. I got the caption bar back. Then I could resize. But it still won't open to the size and positions in the global properties file. It just opens to the last position when closed. Weird.
Edit: NirCmd came in handy. I used the 'win' command to set the window position and size to match the setting in the global properties file. At least for the moment it opens in the size and position I want. Turns out I could have used my own rap.exe (run and position) to do the same thing. Been so long since I used it I totally forgot the name of the thing.
btw-I removed Run And Place Utilities. There are other apps that do it better. I was new to AutoIt3 at the time and the command line params are just a mess. Not worth fixing.
Don't know what that "full screen" feature is about but I don't want to find out either.
