Re: GdViewer PrintShowPrinterSettingsDialog error

Hi Cedric

I solved my problem changing the method call from gdPicturePrinter.viewer.PrintShowPrinterSettingsDialog(this.Handle) to gdPicturePrinter.viewer.PrintShowPrinterSettingsDialog()

I don't know why, but this worked for me.

Anyway, thanks!
