Pen pressure works for me now, I was missing wintab32.dll in Windows\System32 folder. See here for my post #16: http://forum.intilinux.com/mypaint-general-discussion/no-pressure-mypaint-1-0-xp-wacom-bamboo-ctl-470k/

Just wanting to add in here that I have a new Bamboo Create tablet on a new Windows 8 install with the latest drivers (and up to date drivers for EVERYTHING) and neither 64 or 32 bit MyPaint can detect the tablet.

I'm willing to do any debugging needed if additional information would be helpful.

I've got some new informations for all "pressure lost" on wacom tablets.

I've got an old Wacom Pen&Touch that I used to use on a daily basis with mypaint (including 1.0.0) on windows (7 - 64 bits).

I recently bought a new Wacom Pen&Touch.

The old Pen&Touch is labelled CTH 460/K
The new one is labelled CTH 470/K

Here is what I observe.

First : Deleting drivers, Manually removing wintab32.dll then reinstalling drivers doesn't change anything to the following description.

When I plug the CTH 470/K on the computer and I try to use mypaint 1.0.0, I don't have pressure (tablet act as a mouse).

When I plug the CTH 460/K on the computer and I try to use mypaint 1.0.0, I have pressure (tablet act as expected).

When I plug both CTH 460/K and CTH 470/K, on the computer, and I try to use mypaint 1.0.0, pressure works on BOTH hardwares.

When I plug both CTH 460/K and CTH 470/K, on the computer, I start mypaint 1.0.0 and then I unplug the CTH 460/K, I can still use pressure on already lauched mypaint. But I launch a new mypaint instance, the tablet act as a mouse. If I switch between "old mypaint process" and "new mypaint process", I have alternatively pressure and not pressure.

When I plug only CTH 470/K, and launch mypaint, pressure doesn't work. If I plug CTH 460/K pressure still doesn't work on mypaint, but if I launch a new mypaint process, pressure will work.

Everything said here with mypaint 1.0.0 works the same with gimp 2.8

What I deduce :
- This is probably not a mypaint 1.0.0 related problem
- This is not a Bamboo/not Bamboo, not even a Bamboo pen&touch related problem but a Bamboo pen&touch 2010 versus Bamboo pen&touch 2012 related problem.
- I look like an initialization problem somewhere. both tablet works when ever the process has been started when the CTH 460/K was plugged.
- The problem may concern every 2012 wacom tablet, because it look like Intuos (who have entire different drivers) are affected the same way.

According to recent comments in the forum thread, it also happens with intuos4 and intuos3, so it doesn't to be bamboo specific.

I can confirm this problem, I also have it on my Laptop and have made some (so far fruitless) debugging attempts:

A very notable fact is that other wacom tablets work fine with the same setup. Also, I heard several reports from 1.0.0 Windows users who say that Bamboo pressure works fine. Maybe it is only the Bamboo Pen&Touch?
