Can't fix window size

[wp51user]

I'm trying to run WP5.1 on Win10.  The program runs but the window is too small.  Pressing ALT-Enter just blacks-out the area behind the DOS window.  Any suggestions?

Seems like you have a TEXT=50x80 or similar setting in config.txt.
With that the height of the window is larger than its width, Alt+Enter can’t change that.

You could:
Use TEXT=25x80.
Or TEXT=50x200.
Or set the monitor in portrait stand.

You can press Win+F11/F12 to change the window size while it's running. Or, as Jos says, you can change the number of rows and columns in the window. Since you're using vDosWP, you may want to look at the page where you downloaded the system. Search for the paragraph that begins "Lines and columns." There is a large amount of useful information on that page.

Thanks, that fixed it.
