auto refresh

Is there a setting for auto refresh. What I have been running into is when I go to use the next available row....for instance row 5, a coworker can be entering at the same time in that row without my knowledge.  I then fo to refresh and everythng he put in is mixed int o what I put in.  It may have the adress or lacation of the project that I entered and the attachements that he entered.  Is there a refresh rate that we can have happen like every 30 seconds or something of that nature.  The reminder to save your work helps at times,but it's every 10 minutes, and that Isn't frequent enuogh.  A person can add a lotof information in 10 minutes and at the same time your coworker can be adding into the same number and work can be lost...
