I've got a situation where I've got a printer driver (which I'm developing), which works fine in Windows Photo Viewer for all users on my machine... apart from me!
I'm thinking that during development, I must have inadvertently toggled a Photo Viewer setting or cached something for my particular user profile, as when I now go to print using my profile, it fails to start spooling. I think internally Windows Photo Viewer is failing the print.
I've noticed that when I've changed the GDP file for the printer and re-installed, the new GPD settings don't seem to be reflected in the print gui of Photo Viewer, maybe like it's been cached.
So, does anyone know where the user specific data for Windows 7 Photo Viewer is stored?
