Change the theme to the one you used in 2.4 to see if it's a theme issue.

Re: Easy Sharing Across Courses -- Project Format & Sharing Cart
by James Roberts -
Just H,
I realize now that the "Copy to Sharing Cart" shows a waiting icon (turning circle/spinning hourglass) to the immediate right of the source activity.
When you select a location in the receiving/destination course and "Copy from the Sharing Cart", the waiting icon appears in the active tab of the Internet browser (usually in the upper left of the screen).
Moodle indicates that you have to wait while files move; but you have to know where to look for progress!
