Comment 4 for bug 1297692

Sorry for the delay, I've tried the wacom driver with a couple of devices here, but so far wasn't lucky enough to reproduce your problem. When it worked at all, I was able to type with Onboard too.

I can see one more possibility: would you please try setting Preferences->Keyboard->Advanced->Touch input to "none"?

If that does nothing, when you say it is not possible to type, is there any response at all from Onboard? Is there any hint of taps/clicks being registered, keys highlighted? Does the cursor image change when you cross the keyboard's frame? Are any other applications affected?
