Item 'Edit Properties' link fails in FF 22.0

Hi, folks –

  FireFox 22.0 complains about a null "this.widgets.cancelButton" object in the 4.2.c Share app:

Error: TypeError: this.widgets.cancelButton is null
Source File: https://ourserver.ourcompany.com/share/res/modules/simple-dialog_b96a8f73d2d15ccc6d181c7b591055.js
Line: 1
‍‍‍‍‍

  We're getting our feet wet with Alfresco Community 4.2.c on top of Tomcat-7 in turn on top of WS2008.  Things are looking good, but when we fire up the Share interface and browse through the "Repository" into a space and then try to see/change the properties of any content item, the UI does nothing in Firefox 22.0 on Windows-7, and the FF "Error Console" reports the message above.

  Does this issue ring any bells for anyone?  I tried searching for it in the forums first, but came up empty.

  Thanks!

Don

I wiped out the existing Alfresco server and reinstalled the Alfresco and Share WAR files, but got the same result:  clicking on the "Edit Properties" link of an item checked into a space produces no activity in the GUI, and produces the error message above in FF's "Tools" // "Web Developer" // "Error Console".

Any ideas as to what I could try next, anyone?

Thanks!

Don
