Greg,

thanks for the offer, I hope it holds up for my next more difficult 
question :-)
With this one, I've now resorted to initializing the string to NULL, so 
that I get a NULL returned if the user cancels. So this question can be 
considered solved. (I just thought that I must have overlooked a 
standard input box widget, it seems like such a frequently-needed thing.)

Now, I'm stuck with this next topic, and I'll send that one to the list 
in a few minutes. I think that that one is more difficult, but hope that 
this list's expertise may have the right pointer for me.

Regards, Ulrike
