PyKeylogger is a simple keylogger written in python. It is primarily designed for personal backup purposes, rather than stealth keylogging (though it can do that, too). It does not raise any trust issues, since it is a short python script that you can easily examine.
I just realized that the binary version stopped working as of 0.5.1, since i started freezing using py2exe's -b1 option. Apparently of the dozens of people who downloaded the completely non-functional exe, nobody reported the problem. Lucky i decided to test the exe this time (i normally just run from source).
See changelog for other bugfixes. Upgrade recommended for source runners, and necessary for binary "runners".
