I do use SAFARI, and for those not familiar with it, it is the new Apple web Browser.
Yes, I get error pages in Continental.com using SAFARI, and as much as I can be a critic of CO, this one is not their fault.
First of all, SAFARI is a beta product, not a final version yet, and when you install it it gives you a list of warnings that you have to agree before installing (perhaps you din't read them).
Second of all, yes, SAFARI still can't handle many scripts and ASP (active server pages) based web sites, and Continental.com is not the only one with a problem.
So my suggestion is don't use SAFARI as your main web browser. I have no problems using Netscape on my Mac.
