I expect I have misunderstood something here but...
I have read the FAQ HOW TO: Enable/fix playback of various media formats in Opus, right down to the bottom, several times, and I have searched the forum also, and still cannot see how to do what I am trying to do.
If I left double-click an MP3 file from within DOpus it opens the small player window, and plays as expected. I'd like to achieve the same result when left double-clicking an attachment in Thunderbird. At the moment it insists on opening Windows Media Player, which is, I suppose to be expected, as WMP is nominated at the 'Opens with' option in the DOpus File Types setting.
I have selected Play in the Events list for Left Double-Click, but do not know what else to change.
File Type Events for mouse buttons only affect Opus.
File Type Actions affect everything, so changing the default action for MP3 files (probably "play" or "open", but whatever it is it should be in bold in the file type editor) is probably what you want to do.
Since the command has to work in things that aren't Opus, you'll need to run it via dopusrt.exe. I think this is the command you want (assuming Opus is installed in the usual place):
"C:\Program Files\GPSoftware\Directory Opus\dopusrt.exe" /CMD PLAY "%1"
Off the top of my head, I can't remember if you need quotes around %1 or not, so try putting an MP3 with a space in its name on your Windows desktop and double-click it to make sure that works okay. If it doesn't, try removing the quotes.
Note: This is assuming "Open With" hasn't been used on MP3 files to change the default program at some point. If it has, Windows may be overriding the default action for the file type and it's a bit harder to set things up manually (but can still be done).

I understand you are "super-busy", so this can wait until you have more time.
I have made the change you provided to the open action, but it keeps reverting to the WMP command. Odd
Right-click an MP3 file, choose Open With -> Choose Default Program... -> Browse... and then select PlayAudioInOpus.exe, and make sure Always use the selected program to open this kind of file is also selected.
(The program just finds & runs dopusrt as per my post above. The trick is having a .exe you can run with just the filename as an argument, so that it can be used with the Open With list.)
