Thunderbird .eml files not working

[fncll]

I'm a new user. Using UR 1.4d and Thunderbird 1.5.

I Save an email as .eml. I can double-click the resulting file and it opens fine in Tbird.

I can import the message, and it appears to import properly (the item shows the right number of keywords and they are found when searching), but the following problems arise:

double-clicking the "Click here to open stored document" link in the imported item brings up a dialog to choose the application. I choose Thunderbird, nothing happens.

The item is named "Document" no matter what the title of the email or the .eml file is?

How can I import these properly so the link to open in the mail client works?
