I've just posted a beta of PNotes Portable (as originally discussed here). PNotes is a sticky note utility that allows you to post sticky notes on your screen. It has multiple display options as well as a handy feature to schedule notes to pop up. It's small (under 1MB) and works well on Windows 2000 and up. Please give it a try and post your feedback.
PNotes Portable 184.108.40.206 Pre-Release 1
(may take a few minutes to hit the download servers)
Please post any feedback.
UPDATE 220.127.116.11: I've added a pre-release of 18.104.22.168 which may or may not be a stable release. It adds in additional translations and improved scheduling and date handling.
UPDATES FROM PR3: New executable from author to fix help file issue. German language file added.
