I'm also having this problem. I tried changing the settings in slic3r and it still drops the nozzle temp to 200 before it will print. I manually opened the config file and changed the values, but still, no cigar.
When I print, I must wait for the nozzle to start moving, then I reset the temp back to 225. I'm using the 12July 2013 version of Pronterface.
