Looks like this thread had ended, but maybe someone is still listening. I have a related problem which I am hoping someone might be able to help me with.
I'm running RC3 on an DR800SG and trying to read mht files. After loading the files onto my DR they show up just fine and have the typical icon. When I click on one it opens the standard html browser that I'm used to seeing. However, the mht file is displayed as source code (images look like encoded text).
I used WebHTTrack to download the pages, then loaded them into FireFox and saved them as an MHT file. The begining of the file looks like this:
Content-Type: multipart/related; start=<firstname.lastname@example.org>; boundary=----------LpNmeMrTiucxamt7ymTNXR
Content-Disposition: inline; filename=Barsoom.htm
Content-Type: text/html; charset=UTF-8; name=Barsoom.htm
Anyone have an idea why this loads as source code or what I can do to change this behavior?
