Browser Issue in Attaching Assignments and Uploading Grades, July 29, 2009

For Windows Vista/XP users using Google Chrome, and Safari 4.x, there is an issue for students submitting an attached file using the Assignments tool and for instructors uploading grades using the Grade Center. (NOTE: Mac users are not affected by this bug). In both scenarios, the issue experienced is a popup window that appears stating, "Please enter a valid file." Despite having entered a valid file, both students and instructors will be unable to successfully submit either the assignment or the upload grades.

Recommended Workaround
For Windows Vista/XP users, we recommend students and instructors use Internet Explorer to successfully submit an attached file when using the Blackboard Assignments tool and when uploading grades from within the Grade Center.

Alternate Workaround
 

• For those users who would like to keep using Safari 4.x, you must also change the browser's user agent. To change the user agent in Safari, enable the Develop menu (Preferences > Advanced > Show Develop menu in menu bar), select "User Agent" from the Develop menu, and then choose "Safari 4 - Mac" as the user agent.
