Slightly smaller footprint in WisbarAdv3 (beta 6) and I havn't been having any probs with it. A lot of people have been reporting that the betas are using up less memory than 2.x versions too. It's a public beta too and the
latest (beta 6) is active til Aug 30th if you wanted to try it out. If there's still bugs to be worked out he'll post a new beta with some more extended time too.
Using my ppc without wisbar drives me insane, hehe.
