Issues with Resource Manager

Content

Hi,

Is anybody having issues with the Resource Manager? I'm not being able to see or manage images and/or other documents previously uploaded there, here is the error message I get (I've tested in 3 different browsers all showing the same problem):

---------------------------
Message from webpage
---------------------------
The context of already selected resources has been lost, most likely due to a manual refresh of this page.
Please start the resource selection process over. This window will now close.
---------------------------
OK  
---------------------------

Any insight into this problem would be greatly appreciated.
