display -moz-inline-stack is not a display value

well, since these are all AJAX errors, you need to look to AJAX for its compatibility problems.  Honestly, I find AJAX like Cold fusion -- an old outdated proprieitary platform than can never keep up with the rapidly changing browser models.  That is why I never use either, and try to discourage people from using them.

Why not start anew and tell us what you want to do.  THere is nothing AJAX can do (outdatedly) than you cannot do with modern javascript and PHP or ASP.  Of course, if you are fixed on AJAX, ignore my idea ...

Thanks for your comments.

Unfortunately i am not prepared to change the code for that.

A fix would be preferred.

" Honestly, I find AJAX like Cold fusion -- an old outdated proprieitary platform than can never keep up with the rapidly changing browser models." - A very nieve view personally.

Can we see the html for that part of the page?  Those errors may use the word AJAX but since it is from the html validator I am sure they refer to properties and values in your tags.  I really doubt this has anything to with the effect called AJAX, which uses Javascript, server code, xmlhttp object and DOM.  Please also let us know the doctype the page uses, since that directly effects the validation.  You might also need to include CSS that is in the head or an external CSS file since it seems to be about CSS properties but I have an idea the error is about inline CSS.

p.s.  I would disagree that AJAX is outdated and it certainly isn't proprietary.  The actions of many designers, the questions on EE, and the changes in recent browsers would seem to show AJAX is becoming more widely used and accepted and will be around for awhile.  Like all things it has limits but I wouldn't avoid using it or ignore its benefits.  That isn't related to this question though so no reason to dwell on it here but hopefully you find this helpful.

Another thought in case I am right this is about style.  If CSS validation is important or you want to try to make it easy for other browsers to ignore the style the using an external style sheet file or Javascript to see those values could be a solution.  I haven't ever worried much about CSS "validation" and don't see that browser really have a problem ignoring what they don't understand in CSS.  Let me know if you want more info on this though and I can look into it more.

Yes, was a mozilla specific issue. A quick removal of the AJAX tab component and replaced with latest AJAX Tool Kit dll.
