After performing the free upgrade to Windows 10, Directory Opus 11 started crashing every time I right click on a file. It was working fine before the upgrade on Windows 7. The version of Dopus and Windows are both 64 bit. I uninstalled Dopus and installed it again, but this didn't help. When I right click on a file within Explorer the right click menu appears as it should, so the problem seems to be with Dopus and not Windows. I have the latest version 11.17 installed.
