Recently, some of the views in my assembly drawings switch todraft quality. When I switch them back to high quality, the optiondisappears in the dialog box. However, once in a while, when savingthe drawing, I get a message box that says there are drawing viewsset to draft quality, the next time I open this drawing, they willbe set to high quality.

Does anyone know what might be causing this?

Thanks.
