Pen Tilt for Size Dynamics - not working.

Question

I am using Photoshop CS and a Wacom Intuos3 with updated drivers.  (6.1.3-5)
Using Photoshop's brush tool dynamics, I set Size Dynamics to pen tilt - not pressure - yet the pen's pressure still exclusively aff
ects the brush size when drawing.
I would like to have the tilt of the pen control the brush Size, much like using a blunt end of a pencil vs. the sharp tip.
In a separate test, I set the brush Opacity dynamics to pen tilt, and it worked as expected: a near full opacity with a vertical pen
, and almost no opacity with a highly tilted pen. Pressure had no effect, as specified. So, the tilt functionality of the pen defini
tely works.
How can I resolve this issue and get the Wacom pen's Tilt to affect Photoshop's Brush Size Dynamics?

This is a known issue that has plagued PS for many interations. The team has to re-write the code and is not sure when the problem will be corrected so that it will be fully functional. Don't hold your breath for CS5.
There is a really long thread on this.
