Problem with UV Master

Hi - I am reacquainting myself with ZBrush after a couple of years and trying UV Master following the tutorial.

A have imported a simple single mesh as an OBJ to the tool menu and placed it on the canvas. Having bought in UV Master, I pressed ‘Work on Clone’. Unlike the tutorial, the original mesh remained on the screen but the clone mesh did appear in the tool menu.

If I manually bring it in, I can unwrap it and flatten it etc, but I cannot paint on it using ‘Control Painting’. A Red brush appears (for Protect) but the brush tries to paint the UV map on the surface. I have tried every procedure I can think of but to no avail.

I am using ZBrush4/OSX

Can anyone suggest what I might be doing wrong?

Thanks
