CS5 Pen pressure feature stopped working with Intuos 5. Any clues?

[Alex]

<p>I use this feature a lot for most brushes. A few days ago I started noticing the pen pressure feature being completely off after being just fine. When I go to the brush presets (where one can select the pen pressure feature from the drop down menu) under the shape dynamics, or transfer the pen pressure displays a triangle saying the a tablet is required for this feature.<br>

After playing with it for a while and creating a new brush it seems like the feature came back to life and the a few days after same thing happens. <br>

Could I be doing something to mess this thing up while working or does this sounds like one of those weird things that happens. It sure it's annoying when the pen does not talk to CS5 the way it should.<br>

Any ideas, clues or suggestions will be more than welcome.<br>

Regards,<br>
