Cross Browser Support question

I am trying to make my own article publishing site. You can make articles, edit articles , view articles...

All this stuff needs some scripts and I have everything , I think so.

Problem is in Opera. Other browsers work fine but Opera, sometimes, I repeat开发者_运维问答 not every time, only sometimes and always randomly, cannot understand the logic why, but for example if I have 2 tinyMCE textareas, it starts 1 editor, and another textarea is left without transformation it to tinyMCE.

Another Example I have article with lots of pictures in it, and while saving they are processed with php file, and after process user views edited article.

So other browsers are fine, but opera do not like to wait untill php finishes work with pictures and it fires empty article.

Other browsers fire normal articles....

Is there anything I must know, maybe I missed some known bug with opera , or what ?

Problem was in old jquery and ajaxSubmit plugins. I've updated them and everything works fine.
