Hi Mel.
I have had a look at this, am I correct in saying when you try and interact with the flipchart it draws a box?
If so, its just a quick setting that needs changing.
Go to File>settings>Dual mode ActivBoard> Change Touch Input handling to 'Touch or Stylus' and click done. Re-select your ActivPen and you can draw on your flipchart.
I hope this information helps, if not let me know.
