who tells you that message ?
foxpro or your monitor ?

Check your Nvidia Control Panel. There should be some controls in there to set the refresh rate per resolution.

Via the Nvidia control panel, there is nothing there about Refresh. I tried reducing my resolution to the lowest it will go, but it doesn't really solve my problem either. It allows me to technically go "fullscreen"... by that I mean that I don't get hate mail from my monitor about the refresh rate any longer; but as far as accessible screen area for the program I launched in dosbox....I've now got this (below) in not-fullscreen:

to this in Fullscreen... see how my Fox window is so small still? Plus the res change makes everything [besides the Dos part] annoyingly HUGE....

Now fullscreen mode is actually WORSE than regular, it actually makes my working area smaller. Grrrr 🤣 😀 So I think I'm down to blaming either dosbox default settings for the 2ndary window; or else something about the autoexec file for Fox not running through dosbox... not that I would know how to set the default window size in there anyway.

Thanks in advance for any ideas.

My monitor; in it's own courier purple; on a fully black background (like the screen shut off for a sec).
