since may 2016 update i cannot continously scan.

I scan easily 10k plus pages per day. My computer auto updated last night to this new version. Last night I continuously fed 1700 pages into a single pdf and saved it with no issues. Today I get to page 249 and the whole program locks up. Before the pages processed while scanning. meaning I could see them while scanning. Now the pages act like a buffer and wait till the scanner stops before processing the pages. I don't like this new way of scanning. Really really slowing my workflow down. Any help out there? I couldn't find a setting to get it back.
