Hold Shift no longer allows you to select multiple page thumbnails while scrolling through document.

I use Shift and the Page Navigation bar to select multiple pages for extraction.  The follow steps worked up until yesterday.

I would click on the thumbnail of the first page I wanted to select (outlines thumbnail in blue).  I would then move my mouse over to the main document and scroll through the document until I reached the last page I wanted to extract (I have to read each page to determine if it needs to be extracted).  Next, I would move my mouse pointer over to the thumbnail bar, hold Shift Key and click on the thumbnail of the last page I want to extract.  All pages in that range would then be highlighted in blue.

Those steps no longer work.  If I scroll through the document and click the last page in the range, it highlights the last page only.  I can click each individual page thumbnail to create a document range.  But that is not as quick as scrolling.

The organize page feature will not work for me as the images are too small.

I have no idea why my steps no longer work.  It is adding time to what I need to do.
