Hi Ranjit

Sorry about the problem. One way of solving it is to click on the flat head to make it the current element. Then click on the 'flip' button which is the fifth button on the bottom row of button (icons) on the top of the screen. The button looks like an open 'clam shell'. If you still have problems, please send us an e-mail at support@coade.com, and we shall sort it out.
