Yep. OS 8.6 Does not run Safari, or Firefox - both are built for OS X. I think there amy be a FF solution for OS 9.x, but I am not certain of that... the solution might be Mozilla? I can't remember what version of IE will run on 8.6? The biggest limitation is that NOBODY uses OS 8.6 anymore, so your testing would not be very real-world." It would be something like testing with IE $ and NS 4, you cold do it, but nobody would benefit much. Most Mac users are using OS 9.x or OS 10.2.x/10.3.x, and I think more are now on OS 10.x.x than os 9. On Jan 31, 2005, at 5:07 PM, Mark Marlow wrote: > Thank you all for your suggestions.
