specifying an application when using open url
I'm using FMP 10 and was wondering if there is any way to specify an application to use when opening a file. Specifically, the default for PDFs is Preview (for obvious reasons), but in one particular context I need the PDFs to open in Acrobat (to use with a scanner).
ETA: I tried using Send Event instead, but since mostly the files won't exist, I don't want an error message popping up when the path is invalid.
Any help is much appreciated.
