Citar:As you see, Ubuntu Tweak 0.5 only supports the current Ubuntu 9.10 Karmic (later will support Ubuntu 10.04 Lucid). Because maintain the old version spent a lot of time in testing and verifying, make the development of Ubuntu Tweak slow down.

So I decide dropping the support of old distributions. Of course, It supports the distribution who based on Karmic, such as Linux Mint 8. But I haven’t tested, so the report from you is welcomed.
