If "run as administrator" would fix this (follow my logic here), why would the default requirement be "run as administrator - yes" for a function that every single user ever needs? Since every single user ever and always should not be seeing the style list rebuild every time (I see it too when I start a fresh song) it would make no sense for PG to program in a tripping point like that to generate more support requests. That message is part of why I will never reset my cfg and ini files. That will ALWAYS require a style list rebuild. I called PG out on this and they had no clue why, when I see the number of styles I am supposed to see, I still get prompted to allow the style list to rebuild. Just another of the far too many bugs in 2106. We are spending more time looking for and applying band-aids than creating music. Crashing when clicking the stop button, bad display on chord sheets, anomalies when there are style changes and tempo changes within songs, the style list issue, the multi-riff function creating MIDI files when that option is turned off.... this is all stuff that should have been caught in alpha testing before it even went out for us to beat it up in a beta test. These are not obscure functions. This is every day use stuff.
