Jeez, I remember this software from back in the days of my Amiga (early 90's). Brilliant software then, and looking good now.
I have a problem though - I can't get Opus to perform any actions on files, it seems to just pass the hooks out to Windows, so it's using Notepad for .txt files, WinRAR for .rar files, Windows Photo Viewer for .jpg's etc.
I'm using Win7 x64 and Opus v9.5.
Thanks & regards,
