Bad palm rejection makes Fresco almost unusable

I really really like Fresco. The brush tools are great, the interface is clean and easy to follow, and the integration with Photoshop via the cloud is fantastic. I'm using it exclusively on an iPad, and I think the strategy of breaking the painting tools out of Photoshop into a separate app makes a lot of sense for a tablet.

But as much as I want to love this program, I regularly find myself wanting to fling my iPad across the room becuase Fresco's terrible palm rejection makes the application almost unusable. Probably every third or fourth time I place my hand on the tablet to start drawing, Fresco executes at least one Undo, and sometimes three or four. If those happen very quickly as you're putting your pen to the surface, it's very easy to have started a new stroke before you realizes that Fresco has just deleted your last three, and then at that point it's too late to hit the Redo button to get them back. In addition to having to repaint untold numbers of strokes becuase Fresco has undone them, I generally find myself very tense when using the program, because I have to be so careful about how I put my hand down.

PLEASE fix this!
