Maybe you need Waver 1.0. Waver is a Adobe Air app which simply takes Google wave in the Webkit browser and stips off all the browser chrome and runs in its own process. I say all this like its necessarily a bad thing. Its not bad, its actually quite snappy compared to running Google Wave in a browser with many other tabs. The only issues is its not really a new client for Google Wave, its more hybrid rip off of the iphone running wave in webkit. Luckily the whole thing is free and runs on Windows, Mac and Linux without too much bother.
