I haven't tried it for fear of breaking something by replacing the default web browser with one from an incompatible architecture. But that's really not the core issue. My real concern is that C++ binaries from (literally, AFAIK) every other linux distribution will not run on FC4. In FC3, which also shipped libstdc++.so.6 by default, there was a compatibility package (installed by default) that provided the older library, but that doesn't seem to be available any more. Andy
