Bryan described a pretty easy way to replicate.  You can also replicate
using auto-submit:

  https://jira.sakaiproject.org/browse/SAM-1088

Stanford team, I have a patch submitted to that JIRA that addresses all of
Christine's last comments. Any thoughts on my patch?

There seems to be a bit of a push / pull here. The data discrepancy checks
can ensure that a user is not using two browser windows, but the problem is
that it is easy to use the back button and kill an entire submission.  If
you have a class of 500 CHEM 101 students, missing 25 submissions because of
data discrepancy issues creates a gigantic point of pain for the instructor.
 The instructor most likely stops using Sakai if convincing the local team
to modify the code does not succeed.

Considering how easy it is to trip up this error, and considering how
painful missing assessments is to the instructor (re-dos for 25 students is
not fun!), I think we should strongly reconsider our default behavior
related to strict errors in Samigo.
