Version 3.25 generate frozen screen when you repeat activity

On the 3.25 version, when you finish one activity and (on the street again...), STOP... and try to initiate one new activity, the screen freezes and you need to restart the dispositive (losing some information and functions). I need to try with the new version (3.27) but, like Judicial Expert on TI, i think that we have no solution with this little  update. Please, Garmin.... Keep the Costumer !!!.
