In rebuilding after C: drive crash (FYI: three times in 25 year ain't bad, I suppose, twice caused by misbehaving software, once by lightning strike), SM 1.1.17 (Win XP) is "misbehaving," in that it insists on opening online WAV and MP3 audio files and mpg/mpeg video files "internally," rather than using Windows Media Player, which is my default app for all video & audio files.
Before the rebuild, it properly invoked WMP for those filetypes, as does the same version of SM on my similarly set-up notebook computer. Why the difference? My notebook shows those three file types in helper apps with the selection "open it using the default application" (which is WMP), but if I try to install them in the new PC install in helper apps, I get "Warning: SM can handle this type internally..." The MozillaZine Knowledge Base says (or at least implies), that only very basic filetypes (standard web graphics formats and text files) are handled inernally [discussing adding new MIME types in Helper Apps]: The actions you add will not affect MIME types that are handled internally, which include certain MIME types such as image/jpeg or text/plain  and all MIME types that are handled by plugins . Before adding a new action for such MIME types, a Warning dialog similar to the following will be displayed: [the warning about handling this type internally]. Any suggestions on how I can force SM to use WMP for those audio/video file types? -- -------------------------------------------- Dick Baker (contact via http://goon.org/contact.php) _______________________________________________ support-seamonkey mailing list email@example.com https://lists.mozilla.org/listinfo/support-seamonkey
