Subject: Re: TOpenPictureDialog Preview...
In reply to: Brian 's message, "TOpenPictureDialog Preview..." on 14:03:15 04/18/02 Thu

I am puzzled too. If it works in TImage it is registered. The only case I have seen where the TOpenPictureDialog is empty is when an exception is raised when the VCL tries to load the image.

Best regards,
