I posted this in the Wacom forum as well, but they seem to think it's an Adobe issue, so I thought it best to post here as well:
I am unable to work in Lightroom 3.2 for more than ~10 minutes doing trivial tasks like looking at different images, set some values in the develop module etc. before the tablet freezes completely.
Win 7 Pro 64 Bit with latest updates, GeForce 8800GT with latest drivers, Intuos 4 with latest Wacom Driver (but I tried other versions as well...), Dual Quadcore Xeon machine, 14Gig of Ram...
CPU use of the wacom tablet is VERY high when I just move the pen back and forth fast enough with the pointer on top of Lightrooms interface - I can max out one core completely! (like in the win 3.1/95 days with my serial A4 ;-) ).
Funny thing is, after the wacom dies (it never comes back BTW.) the mouse is also starting to act up and hangs every now and then for some seconds. As if the whole pointer-moving-subsystem is getting borked by the wacom crash.
The worst thing is, I found no way to revitalize the tablet other than rebooting - which is impossible 4 to 5 times an hour. I would be much more willing to restart some service or driver every now and then but not the machine.
If I disconnect and reconnect the tablet, even the LCD screens of the wacom buttons stay dark, only the wheel LED is alive. If I connect the USB to another USB port, the tablet works for about 1 second, the pointer moves one millimetre before it's dead again.
I tried all the suggestions in the wacom forum regarding USB ports, energy saving settings etc., disabled the Wacom virtual HID driver (as somebody suggested in the Lightroom forum), tried different USB connections (the tablet is connected directly to the computer, not to a hub), tried all settings in the Wacom Driver...
The Windows 7 Pen stuff is uninstalled, so that shouldn't be it neither.
Mouse flicks and all that jazz are off as well.
But now I'm pretty lost.
On the wacom forum there are a lot of users with this problem and I found several threads here as well.
Wouldn't it be possible for Adobe to directly work with Wacom on this? Users can only do so much about this issue...
Pretty please ;-)
This happens only in Lightroom 3.x for me, not in Photoshop CS4 or any other software I use (quite a lot actually).
And if anybody should have found a solution, I'm all ears :-)
