Ok change of plan. Notes will now be embedded in the blockchain.

For example I resent the previous example to Joric.

It does not use OP_DROP as that would make the tx non standard. The public key is simply the ASCII message. Look at the last output and hex decode 4d6573736167653a205468616e6b20596f7520466f722054686520427567205265706f7274202d2 07069756b. Messages exceeding 120 bytes will be added in an additional outputs.

This took me a minute to figure out, so for others having the same problem:
 * Enable Advanced Mode
 * Look at the Output Scripts section and you can see the hex:
 * I used the converter from brainwallet: http://brainwallet.org/#converter

How exactly does this trigger the message piuk?  Are you looking at every output or only outputs that are 0 BTC then seeing if they have a Message: prefix?
