Hi. I am teaching a stats course this summer and my students are having a difficult time opening a document that was saved locally. It appears that they are clicking in the CODAP file that was saved on their machine and expecting it to open.
From what I can see, they need to open the file from the main menu (they need to have CODAP open in a browser). Maybe the directions on this help page could be extended to include how to open a saved file. Thank you!
In addition to using the Main Menu/Open command, they can also set up their screen so they can see both the browser and the file itself in their local file system. Then drag the file into CODAP. Voila!
