[libreoffice-users] Modified Flag Set / No Changes

Hi
Perhaps you can help.

My students submit examinations done in LibreOffice Calc to a web page.
I bundle them up and download them to a Windows XP box running
LO Version 3.6.4.3 (Build ID: 2ef5aff).  In previous semesters, an older
version was used.  There were no problems like this in previous semesters.

This semester close to one third of the submitted examinations are
being modified when opened by me for grading.  I confirmed by

  1. Open file (usually from the Cygwin command line, but also from Recent Documents)
  2. Immediately clicking the X close icon in the upper right hand corner.
  3. A message pops up asking whether I want to change, dismiss, or cancel.

I typed nothing, yet if I cancel, and then do a save-as, the saved-as file is different.

I have two hypotheses.

#1)
RANDBETWEEN() is used this year in some problems, perhaps it sometimes causes this
problem.  I cannot recreate that behavior, however.  Further, Compare document shows no 
differences, nor does oodiff.

#2)
Some students did work outside of class and the version they used is not 100% compatible
with the version in the labs.  My reasoning is that I found in one submittal (I have not checked
all of them to this level of detail) that one of the fonts changed from something like
"New Times Roman1" to "New Times Roman".   (I used unzip and then a script to split the
various files into lines so that diff produced useful output.)

Any advice?  Is it possible to determine what LO is changing?

Best regards,

David Gast
