Is this point really necessary? Couldn't you just force the static
to lie below all the pages in Z-order? It'll be hidden when=20
any pages are present.

Thanks for the tip. It's nice to have something other than=20

I don't think that the dialogs that make up property pages have "solid" 
backgrounds.
I *think* they are transparent, cause I couldn't seem to get the static to be 
hidden by them.
Anyway, I couldn't make it automatically disappear when there was a page on top 
and appear when not without resorting to changing visibility.
Hope you can prove me wrong, cause I don't like having to change the visibility 
like that
If you can -- please tell me how and I'll update the tip approriately (and my 
code as well!)

Glad it has been of help...
