I originally thought this was a performance issue until I used fiddler to see what was actually going on.
Turns out that the CSS panel that shows the loading indicator is never set to hidden and the div panel that shows the picker/browser is never shown (left as hidden)
# create new review
# click to add content
# Choose Explore Repositories
# Greyed out screen with loading image appaears, and never goes away.
The interesting twist is that fiddler showed a successful call against this URL: https://XXXX/source/cru/TINEVENTS-6/edit-browse/~author%3DXXXXXXX/Reuse_Pathed/
And when I pasted that URL into a new window, I _immediately_ got the repository explorer!.
So i went back to Chrome and started looking at the live source code for the page. By only changing the CSS properties of 2 divs (hiding one, showing the other) I weas able to display the repository explorerer and choose my files. (screenshots on their way)
