I ripped one my CD's using EAC, and wanted to check the id3 tag information by right clicking on the flac file and going to properties. Immediately after i click on "Properties", Opus crashes and has to restart itself. I am running Directory Opus Pro 11.4.3 (Beta) Build 5253 x64 on Windows 8.1 Pro x64 with all of the latest updates. I have included a picture of the error box from DOpus.
That crash is probably caused by a shell extension.
See Crash, exit or high CPU usage when right-clicking certain files.
