The built-in browser in my E51 is surprisingly compatible; even accessing
corporate email web pages and places that other browsers (even earlier
version of Opera on my PC) have choked on.

Surprisingly, I can't get past the welcome page at the free WiFi hotspots
at Panera Bread restaurants here in the US. Lots of folks in the same
stores are using laptops to browse the web, so it must work for them.

You are presented with a welcome page in which you must check a box
indicating acceptance of terms (it is pre-checked in the default anyway)
and click on "GO ONLINE". When I do so, it merely redraws the page.
(I try UNchecking the acceptance checkbox ... that gets me a popup page
reminding me that I must accept the terms ... so that part of the page
logic does seem to work).

All the browser options are at default; which includes SSL, cookies,
Javascript, etc. Any ideas (shorting of buying Opera for Symbian OS)?
