We have an evaluation SurfacePro from Microsoft that has been re-imaged several times but is currently running Windows 8.1 64bit. I was able to upload, view and release all document types using both IE 11 and Chrome.
thanks for the info. this has been strange...2 different patrons using their SurfacePro would get an immediate "Time Out Error" as soon as they would begin an upload of a document.
I guess I will continue to monitor the issue to see if it was an isolated case or some more.
