Wolf,

I'm in a hurry right now, haven't got much time, but I think what you're
looking for is called a 'DropDownList' in Win32Lib. If possible, I will
have a look at your code tonight, or maybe David's got an answer, if he's
not to ill.

BTW, why do you use puts() and printf() next to each other, where a single
printf() would work too?

Bye,
