pager not appearing when sizing window down

pix

Tried to search for this but couldn't find anything. We are noticing that when we are viewing a gallery with the browser window big enough to display all of the thumbnails on 1 page, all is well. But when we size the browser window down, the pager isn't appearing showing that there is now more than one page of thumbnails. You have to refresh the window to see the pager offering a second page.

Update: Disregard this. We worked out the cause... we are boneheads!!!

Hi, link to where this is happening, exactly on your site?
Also, what browser, and what OS?
