Opus crash while viewing *.wav file

Directory Opus Pro 12.2 Build 6109 x64
OS 10.0 (B:14393 P:2 T:1) SP 0.0

If I navigate to a folder with a *.wav file in it and single-click on a *.wav file with the file viewer pane open, Directory Opus will crash. No problem if the file viewer pane is not open. all I need to do is rename a file so I didn't need the file viewer open.

Please zip one of the wav files which triggers the problem, as well as any crash dumps, email them to leo@gpsoft.com.au and I will take a look at what's going wrong.
