The later the build, the better.
Making this browser Internet Explorer dependant does not seem like a good idea, since a can run it on a full-blown Windows 98 install, but not <laugh>a Revenge of Mozilla</laugh> install of Windows 98.
I don't want Internet Explorer, I don't need Internet Explorer, and I'm not about to put it back on my computer just so I can use K-Meleon.
So perhaps a K-Meleon that doesn't rely on Internet Explorer would be a nice switch, since last time I checked, Mozilla was competing with Microsoft.
