Every time I open a MIDI file with "Open with->NWC2" I ends up having it twice in NWC.
I'm pretty sure this is a windows (registry) problem, not an NWC one, but I hope someone can help.
When I right click on a *.mid file, I don't get an option to "Open with NWC2". This would leave me to believe that this file association is something that you have created rather than something that NWC's installation has created.
In any case, I would look at Explorer->Tools...->Folder Options->File Types
Depending on your settings, you may be double clicking when a single click will do ...
Yes, I think so.
It's very easy: right click, then "Open with", then "select program", then "NWC2" et voilà.
From now on you can see NWC2 in the right click menu.
I did, but I didn't see anything odd.
Please note that this kind the file association is operative for the double click and for the standard operations, not for the "open with" (or, at least, so I think).
