frustrating ignorance of file associations

[benpatient]

So yesterday I was working on some stuff, and I was sent a .sea self-extracting stuff-it archive from a client.

To my surprise, this file was not associated with stuff-it expander for some reason...no problem, right? I just click on "browse" and select stuff-it and click "always use this application" and hit "OK" and...

oh crap.

i hit "system profiler" instead of "stuff-it expander"

system profiler has opened, and it sitting there, dumbly, wondering why i sent it a .sea file.

so i close system profiler and right-click the .sea file and try to "open with" another app...at this point, "system profiler" is the default.

so i browse again and this time make sure that i hit stuff-it in the list, and then hit "always use this app" and "ok".

and the file opens.

but then i get another .sea file today.

and it opens by default in "system profiler." So i try and re-set that again to stuff-it.

it doesn't work.

no matter what i do, "system profiler (default)" stays on my contextual menu...

Get Info on the .sea file.

Open the Open With: section and select Stuffit, then click Change All... and confirm it.

Actually, it should show up as an application, but since it doesn't, do that to handle it.
