Loss of Cintiq pen pressure

Hi,

I have come across some unexpected behavior when drawing with a Wacom Cintiq in Flash CC.  Here's what happens:

I draw like normal in a Flash file with pressure sensitivity on.

I open a new file (it can be an existing document or a new blank file, it doesn't matter)

I can draw like normal in the newly opened file with pressure sensitivity BUT...

In the first file I had open, pressure sensitivity and the pen's eraser functions no longer work.

The pen settings go back to normal after closing the second project.

I have been able to replicate this exact issue on three computers and three Cintiqs.  This is a problem for me and others I work with because we often need to have two or more files open at a time.

Here is some technical info about my setup:

Windows 7 SP1

Flash CC 13.1.0.226

Latest Cintiq Drivers

Windows Ink is On in Wacom Properties

I have contacted Adobe numerous times regarding this issue and they can't seem to get through the bureaucracy of who I should speak with to solve my problem.  I'm waiting to hear back from a specialist now.  Has anybody experienced this and found a solution?

Thanks!
