Hi;
Just as a point of interest we too were allowed to use work computers during 
lunch and break for so-called personal business.  It seems that one well 
intentioned soul (not me thank God) was using this time for personal banking 
complete with passwords etc.  The problem was that all computer activity was 
digitally recorded and saved personal or not and oddly enough nobody knew 
how to erase his personal activity.  The right people would have had no 
problem "reviewing" his work and would have seen all the financial info 
complete with log in info and account numbers that were input during lunch.
Thank God for retirement
At any rate, point is be ware of to much personal use of work computer 
allowed or not.
