Bugfix Empty menu: In previous version an empty menu was shown sporadically. After pressing back button the menu was shown correctly again. Potential root cause is the call of the Set Top/Bottom Frame function while updating the cursor position. To handle multible updated is previous toggle bugger has been changed into a ringbuffer allowing to send several update frames after each other. Beside this some old debug code has been removed.
