Empty/blank pages by enlarging scanned documents

I use PDF Architect V 1.0.41. It shows the content of documentes scanned as images as long as they are scaled in thumbnails size. By enlarging the pages appear blank and it need minutes before a single page can be seen. The more pages in the document the worse is it. I have no problem with other viewer. Any help?
Thank you.

Hi,

have you tried changing the graphics options yet?

Thanks for the hint. GPU acceleration was on. No change when switched off. So I tried to do what all desperate will do: I reinstalled the software. Now it seems to run. Thanks again.
