Perhaps too much is getting redrawn > at the GTK level; that could be a bug. I don't know, it seems to just be the scrollbar; again, the standard themes seem OK (so I don't think this is a critical problem), there's just something very slow about my theme. Menus are very slow too, when I use them. One thing is that GTK seems to do full redraws of components by default, and rely on graphical double-buffering to make it look smooth. This seems to be a fundamental aspect of GTK though, so I guess it's not easy to fix. -miles -- The secret to creativity is knowing how to hide your sources. --Albert Einstein
