Hi Taras,

thanks for your answer.

Which is Chrome 15, Firefox 8, IE 9?

What do you mean with "tab crashes"?

This is a subsequent error.

This is the main problem. There should be at least the post parameters 
extAction, extMethod, extTID set, which is obviously not the case.

The problem is, that I cannot reproduce that, using IE8, FF7, Safari 5.1 
or Chrome 15

A bug has been fixed for 4.6.0 and the upcoming 4.5.8. Maybe there is 
another nested form tag, but to find it I would need to reproduce it.

Did you try a clean 4.6.0 install? If it fails for you, can you give me 
access to that plain install where the error occurs?

Put this in your localconf.php to activate the old EM modules:

$TYPO3_CONF_VARS['EXT']['showOldModules'] = TRUE;

Please use firebug to look at the response when switching to the 
configuration tab. This response contains HTML in the "result" property 
and this HTML must *not* contain a <form> tag.

No need to debug at first, because I assume that ExtJS works in general.

Thanks. Seems there is a problem we need to tackle.

Kind regards,
