I was wondeinrg if the "preview" size can be defaulted to " Fit to Window" - currently it is defaulted to " Fit to Window Width" and we are trying to view some pictures, every time I select a new document I have to right click on the picture and resize from "Fit to Window Width" to Fit to Window.
We find this very annoying too, when trying to take a quick look at a selection of photos. Even if the TRIM option to "use same viewer window when viewing electronic documents" is selected, the view resets the size for each new document. The only workaround we have found is to make sure the file type is set to bypass viewer, and install a third party software package that will open new documents in the same application window. Paint.net is one example. However, it has the disadvantage of keeping previous documents open, using additional system memory as you go. You can use Ctrl-W to quickly close them periodically though.
