P: Touch Workspace appears broke (thumbnails missing)

Found this thread in the U2U forum, and can confirm it is not working for me either. The OP of that thread is using a Surface, while I'm on a Wacom MobileStudio Pro, so I don't think it is a driver issue. Here's what happens:

- starting in Grid view with a few thumbnails showing in a folder, and one photo selected

- tap the Touch icon

- the view switches to Develop, and all thumbnails vanish

- pressing the G key switches back to Grid view, and thumbnails appear in the main area, but Filmstrip is empty

- changing sources via the Folders panel never populates the Filmstrip, though the main area loads with thumbnails

- restarting Lr is the only way to get it back to normal

This is not a function I use, but I did use it once on 7.2 and it did work. Just wanting to bring it to the team's attention.
