I'm running a self-hosted Moodle 2.7 and I have a teacher that's using a GPad (Google's new tablet) to download and view student submissions to the assignment module. The only problem is that he can't get the assignments from the view/grade all screen. When he clicks them, the downloads always fail.
This is perplexing, because he is using Chrome and is able to download items from the front page of the course.
I'm not having problems on any other device - downloads work just fine in the "View/Grade all" interface on all the other devices I use.
