Directory Opus 10 has stopped working

Repeatedly receive the subject message for no consistent reason. It sometimes occurs when I right click a file, sometimes when I click to exit, and sometimes after I have exited and don't want it to restart. See the attached jpg screen shots of the messages. Very annoying - help would be appreciated.

QtCore4.dll is part of QuickTime, you could try uninstalling that.

I will try that and let you know the results. Whitey
