[Resent without screenshot, as the webview showed only the screenshot] Hi, I am stumped, I have a Perl script that accepts files as input, reads them and writes a new file (in the same folder as the original file). Used Platypus to create an application that accepts dropped files. Last updated the Perl script six weeks ago (October), 'updated' my application back then. The Perl script, run from the command line, and the application created in October still work fine. Now, using the very same Perl script Platypus creates an application but the application does, so it seems, nothing apart from launching when I drop a file on the new application. Is there any special setting beyond the checkbox 'Accepts dropped items'? Or why would what worked six weeks ago, now have stopped working? Any updates to Perl, the OS, or Platypus since then (I am not 100% sure, my update to Mountain Lion might have been after when Platypus last successfully created the application). Thanks a lot in advance. Lenny
