View Pane Refreshes on PDF Files

I just went through a complete uninstall and reinstall of X1 (version 8.1.0.0 according to the version showing in the control panel).

After indexing I did a search that gave me a mix of word, excel, and PDF documents.

Word and Excel documents appear normal in the viewer and I can scroll through them and read them.

PDF's are repeatedly refreshing back to the first page every 5 - 10 seconds. I haven't checked every PDF but I did notice that one image only PDF did not have the same problem.

Indexing had completed so the behavior would not have been caused by X1 reading the document.

Anyone have any thoughts why X1 exhibits that behavior with PDF's?

Thanks,
Bill
