Hi,

In the article File types and download actions (under Adding a download action, SeaMonkey and Mozilla Suite), you added that "The actions you add will not affect MIME types that are handled internally by SeaMonkey or by any plugins". I thought so too, but I added a helper application for text/csv to open .csv files with C:\WINDOWS\notepad.exe and it worked, even though, normally, csv files are handled internally by SeaMonkey, by opening the file as text inside the browser. Try it yourself, by using "File -> Open File" and browsing to a .csv file, if you have one saved (I export my address book as .csv for backup) and then adding a helper application for text/csv. Did you have something else in mind? Alice 01:29, 19 September 2007 (UTC)

In the past I responded to a couple of SeaMonkey Support questions on not being able to define specific applications for opening image links or attachments, and also was involved in a recent discussion on problems with the Windows Media Player plugin causing similar issues [1]. Thus, I had another look at this article and made those additions. Feel free to modify if they are too general now. --Rsx11m 23:17, 19 September 2007 (UTC)

OK, I see what you mean. I tried adding a helper application for image/png and I got a dialog that SeaMonkey can handle that type internally. I also saw the bugzilla bug 58554 report you added to the article. Alice 01:42, 19 September 2007 (UTC)

Yes, that's the one on the image MIME types. I didn't add 363155 as it is on WMP only and thus too specific for this article. --Rsx11m 23:17, 19 September 2007 (UTC)

I added an image of the Warning dialog you get in SeaMonkey when you add internal types to the article and also a link to the forum thread you referenced. Thanks. Alice 13:26, 22 September 2007 (UTC)
