I have a problem opening the Attachment dialog on IE9 and some version of Zimbra webmail client. I'm not a administrator or something so i don't know any versions of the client etc.
This only happens on IE9 on all the accounts.
The problem is when clicking the button "Attachtments" nothing happens... IE9 gives the errors through out the development tool:
Translated, the property of the method getHtmlElement is not supported by this object.SCRIPT438: De eigenschap of methode getHtmlElement wordt niet ondersteund door dit object
Startup1_1_all.js.zgz?v=120410004816, regel 17839 teken 1
I only got this problem with IE9, Chrome works perfectly
