How To Record A Speed Painting Without Showing The Cursor?

Hi everyone, I have been recording speed paintings in Corel Painter X for a while but I never knew how to remove that white circle which is the cursor but now I really, really need to know, because they are meditative paintings and the cursor is not good on them. I used camtasia 5, already tried to choose an option in camtasia to remove the cursor but it doesn´t work, perhaps only with the pointer cursor. Do any of you know how to do that so I can record a speed painting where you can see only the brush strokes but without the cursor?

To watch my speed paintings, please visit http://www.youtube.com/easymeditation

Thanks.
