Bill,

I just checked, it's stored in this registry key: HKEY_CURRENT_USER\Software\Microsoft\VisualFoxPro\5.0\Options\DebugEnvironment "0" = debug frame, "1" = FoxPro frame.

>I keep losing the Option Defaults that I set in the Options window.
>I have verified that I'm using the same Foxuser.dbf and that I press "set as default" before closing VFP5.0.
>Specifically I keep having the debug set back to "debug frame" instead of "foxpro frame" among other things.
>
>Can anyone think of anything that might be causing this?
