I had a play with this. It would seem that the static text control uses the window title property to store it's string, (256 characters), although the resource editor allows you to create much long strings without reporting an error, (I did just that).
I guess I have never had the problem before as I have never tried to use a static control for anything other than a few words.
Windows has a reasonably good built in help system within the API, but I guess you have not got there yet in your Petzold!
