Ah, then forget about debugging and start thinking about strategies for
getting back at the SOB. ;-)

If I try to call CW_FSLIDER from the prompt it will complain that the widget specifier is invalid (clear enough, I'm not giving it a proper input). If I then give it the uname keyword it'll mention nothing about the invalid widget specifier, but go straight to uname not allowed in call to CW_FSLIDER. I still think that is very strange :-|

My guess is the widget ID doesn't point to the widget you think it does.
You might be able to use WIDGET_INFO and its various keywords to gather
information about the widget and see if you can figure out what is going
on. The CW_FSLIDER widget should be a base widget (use the TYPE
keyword). There is no question the code assigns a UNAME to this widget,
so the reason you can't find it appears not to be the fault of the
CW_FSLIDER program itself. :-)

Cheers,

David
