I tried to apply my tool "fl_SwingTriplets.lua" to the second staff of this score.
NWC crashes just after my tool is finished.
As far as can tell, it's not my tool to blame but it's a bug of NWC. ;D
While investigating, in some cases instead of the unhandled exception I got the "Pure virtual function called" message.
I think there is very little I (we) can do, beside using some obvious workarounds.
It's just for the records... or for the next version 3. ::) ::) ::)
Ops! I decided to keep for myself the "beta" version for a while, then I forgot to publish it!
Updated.
