Dynamsoft TWAIN Products

In our application, the user can scan many pages, and choose to create a pdf using a subset of those pages. Once the user selects that subset, we send the user to another page to title and save the pdf.

When the user returns to the remaining scanned images, we see a strange white box appear in the thumbnail list. It is linked below.

Do you have any idea what this is, and if there is a way to fix it?

Edit
I notice that it goes away when I scroll. Could I force a refresh of the thumbnails?
