I have this one file that is for string quartet. Lots of switching between arco and pizz. Finale used to handle this file correctly until I upgraded recently to the latest. Now, it starts off fine, all the keyswitches fire, but somewhere about 1/2 of the way through, for just first and second violins, the keyswitches get stuck on pizz and do not flip back to arco no matter where I place 'arco' in the score. The cello and viola do fine. Any idea what that could be all about?
