I've got a DWW-700H from Digital WorldWide, and I can't get it to calibrate properly:
When I run the 4-point calibration (4 corners), after the calibration, any press on the panel (doesn't matter where) will move the cursor to the upper right corner and click.
When I run the 25-point calibration (corners of a 4x4 grid), any press on the panel will move the cursor to the lower left and click (which catches the Start menu and brings that up)
I've done some

ing but haven't seen this exact problem, but have noticed that there is some flakiness associated with the resistive touchpanels.
What's more odd is that the screen *was* working fine for about an hour after the install, then while driving, the computer played the USB-device-disconnect sound and popped up a window saying that it couldn't recognize the device. After reboot, Windows recognized the touchpanel fine, but it won't calibrate.
Sounds like something died on the controller. I haven't taken it out to open it up yet, since I don't know what I'm looking for. Anyone have any ideas?
Also, I sent a message to Digital WorldWide, but the last time I sent them a message I never got a response...
