Thumbnail display issue in Dopus 10

I am having an issue where folders and pictures are distorted when viewed in thumbnail mode. This started today with no new installations of programs or issues. I am running an up to date copy of Windows 7 64bit. I did not download the update that caused the recent graphics driver issues from Windows update. I haven't noticed any other issues in other programs. It also does not do it consistently across folders or even within a folder. So some thumbnails look like above and some look normal, even within the same folder. Any suggestions or questions I can answer? Thanks.

Do you see the same thing in Explorer?

Duh, I didn't even think about that. Yes it does show the same. Any ideas?

Updating to the latest video drivers may be worth a try (you can usually get more recent ones from the video card manufacturer's websites than Microsoft has on Windows Update).

Alternatively, it could just be a corrupted icon cache - you could try clearing it.

Tried the icon cache, no luck. On guess, I ran CCleaner and it cleared it up. No clue what really caused it.
