Turn ARC On for 64bit compiles, don't make MIDI, fix various issues with bridge and windowIndex for ARC, fix parseArgument data type warning<br></blockquote><div><br></div><div>Curious (ok, ignorant). Why use ARC for 64-bits but weak for 32-bits? WOup;don't it be better to go with one approach for both?
