It's also true, unfortunately, for more commonly used widgets like
Text widgets, as I discovered this afternoon after converting my
program to use the above sequence.

Trying to put a scroll bar on a text widget works fine when using
XtInitialize/XtMainLoop.

When using the above sequence however, you get an error message:

X Toolkit Warning: No type converter registered for 'String' to 'EditMode'
conversion.

and you get a Text widget with no scrollbar.

Guess I'll go back to XtInitialize/XtMainLoop for awhile.

P.S. - Note to X Consortium folks: I have a short program (< 100 lines)
       which demonstrates the above, if you want it.
