Hi, I have two versions of pd-extended on my mac: pd-extended (0.39) and pd-0.40.3-extended. I want all pd files to be opened with 0.39 by default. Instead os x tries to open all Pd files with a version (0.40.3) which I deleted some time ago. oh, how I hate stupid MACOS X! anyway, how can I change that. I tried to use applications like xray, but whenever I change the settings to the older version it gets overwritten by that fascist OS that thinks it is cleverer than me. marius.
