Pretty good, but only skins title bars and window borders (not the taskbar, or for some reason the title bar of the Task Manager). I tried enabling the option to use "extended skinning", which it says will skin toolbars etc as well, but it didn't seem to do anything. The thicker window border also makes dialog box buttons appear too close to the edge of the window (although you can probably make the borders thinner by editing the skin). It didn't seem to reload on reboot either, despite setting that option. Oh, and I got a weird bug where maximising an explorer window made half of the toolbar transparent so it was just the desktop wallpaper. I'm not complaining, just pointing out the bugs - it is only version 0.1, after all! It does only use 2MB of RAM though, which is impressive, and I can't notice any slowdown - Win2000 really fast even in Virtual PC. I posted link on OSBA this is what they found out
