Hat geantwortet auf: Boogie Board won't eraseModel wt14029 started to not erase also. Tried three different batteries but nothing worked. Finally found out after reading some of these reviews, we have to PINCH TOP LEFT corner while pushing the erase button. One of the previous posters was confused about which corner is which. I am considering the top left as the top left as you are viewing the board so you can read the words "boogie board" right side up.
