No problemo. Use both Netscape 4.7 and IE 4.5. No problems with either, although I prefer to use Netscape.

For their own internet access, my kids use 2 different PowerMac something (hand me downs from dad), OS8.6 and Netscape 4.7. They don't complain so I am assuming that all is fine. (but then they do go to the ChipBoard either).
