Hi, thanks for the follow up!
I've done what you've suggested and the file shrunk 3 bytes. Then I checked
the file with http://www.htmlhelp.com/cgi-bin/csscheck.cgi and the file
looked clean.
I thought: This is it! Finally I tried the css validator again with the same
result. Using firefox it gives the exact message you mentioned: Servlet has
thrown exception:javax.servlet.ServletException: Timed out.
I browsed the file and found no apparent errors...
Then I looked at a css class with a "&" in its definition. After deleting
it, the file validates.
With errors that weren't there before, but it validates. Now I just have to
figure out the errors.
Thanks!
Cláudio

It seems to come from the CSS Validator, so it's apparently a bug there,
though the ultimate problem is in your style sheet.

So the problem page is http://www.ua.pt . It has valid markup, and the
first few style sheet referred to by it are checked OK, but the problem
seems to be with the style sheet
http://www.ua.pt/css/StyleSheet.css
which results in the message
Servlet has thrown exception:javax.servlet.ServletException: Timed out
(and probably the 500 error code, but IE doesn't tell).
Checking with
http://www.htmlhelp.com/cgi-bin/csscheck.cgi
which is an old CSS checker, largely limited to CSS 1, but useful for
many purposes, I find that the style sheet begins with

(or, technically, undefined octets that become such characters when
interpreted as ISO-8859-1 data), which looks suspiciously like a Byte
Order Mark (BOM) at the start of UTF-8 encoded data. That's more or less
garbage in CSS terms, and seems to trigger a bug in the W3C CSS
Validator.
This should get fixed if you edit the style sheet using a simple editor
and remove the extra data at the start, or open it in a UTF-8 capable
editor and save it in ASCII encoding (or ISO-8859-1, or something like
that), which should result in having the BOM dropped.

I guess the CSS Validator somehow changed its processing of character
encodings, then.
