Right--the way I've handled plotting (in the command line, that is) is I set the BROWSER environment variable to cygstart, and Sage uses this variable, if it's set, in determining how to open image files. cygstart is a program in Cygwin that just opens a file with the default handler for that filetype in the registry. I believe if no default handler is found then the standard Windows pop-up for unknown file types, allowing you to specify a default program (or "app" as it now says on Windows 8 and up) to open files of that type. So in other words, the behavior (and indeed Windows API calls) are the same as when you double-click a file in Explorer. -- You received this message because you are subscribed to the Google Groups "sage-devel" group.
