Illinois Compass 2g, Submit button does not work

I am trying to make a submission in Compass 2G. When I click the Submit button, nothing happens.

When the text editor turned off in an assignment, it seems that it also turns off the Submit button functionality for the assignment.  The button appears as if it should work but nothing happens when you click on it.

If the editor is on, you will see a Microsoft-style bar of formatting buttons, with a tab in the upper-right reading "Text Editor is On". If the editor is off you will not see the formatting buttons, and the tab in the upper-right will
indicate "Off."
