Unfortunately I'm not sure of anything. I have no experience on writing widget based idl programs, and is merely using somebody else's code :-(

the only thing I know for sure is that it did work once upon a time, but I'll try to have a look at what you're suggesting.

I am however still very puzzled about the way in which this is failing. 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 :-|
