Current issues:

1)The wallet never seems to synch even after its downloaded the blockchain. This could be something to do with the time differential on ubuntu. Its largely cosmetic because in theory there are always transactions occurring so its always going to be out of sync. It doesn't affect the functionality. However will look into it.

2) The wallet crashes on Windows XP after the blockchain reaches a certain size. This seems to be something to do with Qt. Memory leakage? Codec? Qt crashes a lot with all the coins. It crashes just using the creator sometimes.

The virus warning on the zip is a false positive. Eset also flags all self extracting archives as potential threats automatically. Its bundled with Windows so maybe ms just doesn't like people using third party software....
