earlier this morning when i was showing my friend my speedy pro sandwich, i demonstrated the stop watch function to show him what the buttons are. after i pressed the start button (top), i was expecting to see the center sweeping hand starting to move. however, that did not happen. instead, the second hand on the left subdial stop moving. i was puzzled, but i quickly pressed the top button again. then the second hand started to move again. i then pressed the start button again, the function resumed. i thought it was just my eyes that i saw it wrong. however, it happened again tonight when i was at the hospital during my internship. i was trying to use the stop watch to time myself for a task, that's when it happened again. i am very concerned about this issue. is this normal??? the speedy pro is very new, so i hope nothing is wrong with it. do you speedy pro owners experience what i am talking about? many thanks.
