Possibly so; FOX version 1.0 really only supports one main window 
(instance) per application. This problem is being addressed for FOX 1.2.

OK.

Sounds like you might want to instead use a dialog box for that second 
window (the entry/update window). See the dialog.rb example program 
(among others) for an example of how to create and use custom dialog boxes.

I don't follow this. The 'show' instance method is defined in FXWindow, 
which is the base class for all of the windows & widgets in FOX.

See previous recommendation about making the second window a dialog box. 
 From your brief description, it sounds like the 1st main window is 
always shown, and is used primarily for display purposes; but the 2nd 
window is transient, and used temporary to add or update table entries.

Hope this helps,
