Subject: TOpenPictureDialog Preview...

I have created a new TDibGraphic class for reading/writing PPM format files. I have updated Envision.Inc and enreg.pas and the class is registered OK with TPicture at runtime. I can use a TOpenPictureDialog to select the filename, read the file with a TPicture object and display it with a TImage. BUT the TOpenPictureDiolog does not display the preview (it does this fine for all the other registered types). I have looked inside the VCL source for both TOpenPictureDalog and TPicture and I am greatly puzzled. Am I missing something obvious ?
