Yes, you're right.
I didn't understand what you are trying to do at first.

As far as I know, a modal dialog is only modal to it's parent window, not to windows from other programs.

To make something you want, you will have to do something like the Windows XP shutdown dialogbox:
Make a screendump, show it on top of everything, and place your dialogbox on top of that.
See http://www.codeproject.com/KB/dotnet/DimmerForm.aspx for an example (.NET)

But as said before, I don't think that is something you want to do to your users...
