Maybe this doesn't happen on other device/WebOS combos but on my Verizon Pre 2 with 2.1.0 Meta-doctor the exhibition mode constantly is reverting back to the standard clock. It does it every single time the device restarts, and has on other occasions as well. I find this EXTREMELY annoying. I know with the Pre 3 it's supposed to be able to distinguish between touchstones (obviously only new touchstones as well) so that different exhibition apps can open for different locations but it would be nice to be able to at least specify a default app for it to open to if not make it always open the last used one even after a device restart.
