Don't ask me why I didn't just get a pencil and paper, but I was taking down some measurements around the house using the Transcriber mode in Notes. Ever since then the phone will intermittently do any/all of the following:

Touchscreen stops responding
Messaging/IE/Phone, etc. keys on face do not respond.
Touchscreen Outlook link responds intermittently.
QWERTY kb does not respond (but you do get Alt and Caps Lock lights)
When you finally get into the email list (usu by using Start menu), clicking on an entry acts like a click+hold and brings up the Delete/Reply menu instead of opening the message.

You get the idea. Who knows if there's a correlation between using Transcriber and this problem, but it's clear the issue began immediately after exiting that mode. I have tried soft reset and mem maid cleanup.

Any thoughts?

Found a workaround, lol. When the phone misbehaves (texts wont open, kb doesn't work, etc), black the screen, turn it back on, Voila!, it works fine. Black the screen again, turn it back on, Poof!, it fails. This toggling of the phone's behavior can be duplicated each and every time.

I think I see a hard reset in my future....
