I've just posted a pre-release of Task Coach Portable. Patrick Patience created this one and this is a finalization of his work with a few minor changes: Task Coach was updated to 0.69.1, the launcher was updated to correctly display the missing file name, the files (EXE, DLL, PYD) were all UPX compressed and the ZIPs recompressed, the icon was updated, the splash fade was removed and an official splash screen was added.

As this has gone through a good round of testing and there are no major changes, it should be release-worthy and if there are no issues, it'll be released next week. Please give it a thorough testing in the meantime.
