Can't type anything in inputs or textareas

I have a problem: I've add a Jquery UI drag-n-drop widget to my page, but after that I can't type anything into inputs or textareas.

I use jQuery 1.4.2 and jQuery UI 1.8rc3, and tiny_mce for convert textareas into WYSIWUG editor (I've tried to disable tiny_mce). When I put $("input").click( function(){ alert('clicked!'); }); - it's w开发者_开发知识库orking(I have an alert).

When I get focused to any input I even can't refresh page by F5 and go to the next element by Tab key.

There's a page: http://cms.reactive.by/test.htm (click to clip2net.com/clip/m7787/1269022358-clip-3kb.png to see that jQuery UI is workong)

And yes.. there's no errors in FireBug.

I hope You can help me to understand what's wrong with this code.

Your WYSIWYG editors all fail because most of the JavaScript files the editor tries to load, for example:

• http://cms.reactive.by/test_files/themes/advanced/editor_template.js
• http://cms.reactive.by/test_files/plugins/imagemanager/editor_plugin.js

return

I guess that's a error message?

The Firefox error console complains about every such file with a syntax error, should be easy enough to sort out.

You can only achieve this by defining either maxlength="20" or readonly fields..
