Are you able to reproduce the bug i originally found?

1. Unplug your wacom
2. Grab QtC. File-> New -> QtQuick UI
3. Default everything to create the Hello World

At this point you might get random popup windows showing a driver
error, then switch back and forth Quick Designer view and code view,
if you make it very fast (use F4) you get the bug in a few seconds.
QtC eventually locks, or gets empty designer views.

I noticed a lot of qmlpupet.exe zombie-like processes in Windows.
