Thanks a lot for your input!
Of course, using the resources from PEP as templates would be the natural thing to do - for
some reason that hasn't occured to me #-)

I've now set it up exactly like that and I also split the dialog title from the message, so you could configure different text styles for each.
You could also set some title bar background for the dialog window, if you wanted.

I'll have a closer look at the word wrapping code. I'm currently not sure if I'm going to implement text wrapping at all, but I will give it a try.
I'm not planning to use these dialogs excessively and currently all the text displayed is static anyway, so it might just be easier to do the formatting in PEP - also considering the likelihood that the result might look more pleasing when done manually.

Thanks for the phone call offer - I'm currently ok using the forum, but maybe I'll take you up on it one day.
I'm located in Germany, so there's also the time zone issue...
