Microsoft OneNote can to automatically switch between pen and touch input. This means that you can use the pen to write on the screen and use your fingers to scroll/zoom without having to select a different tool in the toolbar. Unfortunately this feature was not working on my new ThinkPad Helix. I would write on the screen, but when I would scroll, my fingers would end up drawing a line. Here's how to fix it.
Check OneNote Settings
Before you do anything else, make sure this feature is enabled in OneNote. In OneNote 2013 (and I believe 2010 as well), go to the
File menu and select
Options. Look in the
Advanced section under the
Pen heading and make sure
Automatically switch between inking, selecting, typing, and panning is checked. See the screenshot below.
UPDATE (7-11-2013): I found that the Wacom driver has no effect. The key is whether or not the Wacom digitizer is enabled/connected before starting OneNote. The ThinkPad Helix has a switch in the pen silo that disconnects the USB connection to the digitizer when the pen is in the silo.1 If the digtizer is activated after starting OneNote, the pen will still work, but the problem described above will occur. Closing OneNote and restarting it with the pen out of the silo appears to fix the problem.
Wacom Driver If you still have a problem, then try installing the Wacom Enhanced Tablet Driver. Go here, choose
Tablet PC as your tablet mode, and select your operating system. The version 7.1.1-12 drivers (May 9, 2013) fixed the problem on my ThinkPad Helix under Windows 8.
However, the driver update did introduce one new problem. When the Helix is docked, touch input does not scroll the page in OneNote. Zooming still works, but it centers at a strange location. I can still use my finger to scroll the list of pages as well as navigate the interface. Once I undock the tablet, touch scrolling works again. This problem is less annoying for me than the lack of automatic tool switching, so I've decided to keep this configuration for now. Your experience may vary.
