Crash at Desktop

Directory Opus Pro 11.17 Build 5829 x64
OS 6.1 (B:7601 P:2 T:1) SP 1.0 "Service Pack 1"
Windows 7 64bit

I can't tell from when. Whever I navigate to Desktop Folder (not C:\Users\KIYO\Desktop, but the top of tree), Opus crashes with error dialogue written thus.

"The error (0xC0000005) occurred in thread 'dopus_lister' at address 0x000000013F0A0995."

Crash, exit or high CPU when viewing certain directories is the best place to start.
