After upgrading to 6.2, I can't add modules to pages any more.  The drop-down list looks like a field and is stuck on "HTML" with a "select" link next to it that does nothing.  Is this a known issue (I've been looking)?

That's not it.  When the Modules window opens, despite the other drop-down fields in the window, the Module field appears as a regular disabled field.  The text is not editable and to the right is a "select" link that does nothing.  Selecting "All Categories" from the Category drop-down does nothing but close the window.  When I reopen, "All Categories" is still selected, but there is no change to the Module field.  SEE GOOGLE DOCS LINK.

This is in IE9 in compatibility mode.  Without compatibility mode, the only difference is that the "select" link does not display.  In Google Chrome, the "disabled field" and "select" link are meshed together.

I'm having the exact same issue. Upgraded a DNN PE site from 6.1.4 to 6.2 and now the "Add Module" button isn't clickable. I tried in Chrome, FF and IE8. I tried tabbing to the button and pressing [Enter] or [space]. Doesn't work.

I upgraded a 5.6.7 CE site to 6.2 CE on a test server and having the same issue. Thankfully that's just a test version. 

I'm going to have to revert the PE site back down from a backup because I have to do work on it.

Not good and not happy. :(
