I don't believe Liberty uses Blur, but I'm not 100% certain. Yes, Catch is available from the Market and is similar to Evernote (morphed out of the old AK Notepad, I think) and is a general note/pic/etc. sync app. As you suggest, if any other DX users are experiencing this same problem with Catch, I'd love to hear about it.
I just wiped the data and cache from the app, then uninstalled it and reinstalled it - no change. Looks like I might have to head back to Evernote unless someone else has another suggestion...
