As the title says, Im getting an error message when im trying to print (to any printer) with NP++.  It happens when I push the ok button on the print dialog (or choose file-> print now).  It doesnt happen with any other program that i have that prints, and it doesnt matter what version im running (ive tried installing older versions to make it work with no success).

Im running Vista x64.

Any suggestions?

Thanks,
Mike
