VB.net : Printer Dialog Box does not appear

Turns out there's an incompatibility with some versions of windows 7 (possibly 64bit versions), which prevent the standard PrintDialog box from appearing when invoked.

This can be worked around by setting the UseEXDialog property to "True".

This forces the dialog into windows XP mode, allowing it to be shown correctly....

Annoying eh!
