bug 464309 should better dupe since it's a TB bug

[I've unmarked this as a duplicate, tried to make the description, well, more descriptive. And, I've attached a screen capture annotated to point out what I'm trying to describe) When viewing all headers, a header that is too long for the window appears truncated. However, if one clicks on the header and drags it, the header scrolls horizontally and one can see the remaining text. This is a really cool and clever feature. Since there's no visual indication that the header will scroll, the feature is unfortunately hidden and most will just think that Thunderbird is truncating headers and that you need to "View Source" to see the entire text of a long header. Reproducible: Always Steps to Reproduce: 1.Set View -> Headers -> All 2.Select Message with headers too wide to fit in the message window 3. Actual Results: The long header looks as if its been truncated. However, clicking and dragging near the point of truncation scrolls the contents of this individual header line. Expected Results: Some indication that the header can be horizontally scrolled to see the additional text should be presented.

(In reply to comment #4) > Some indication that the header can be horizontally scrolled to see the > additional text should be presented. same hint in Normal Header mode would be nice. FWIW, irrc the drag and select-to-the-end capability is there to allow for copy of the text I didn't find a duplicate for this (which is surprising, OTOH I don't remember ever seeing such a bug) but you are welcome to search through https://bugzilla.mozilla.org/buglist.cgi?query_format=advanced&short_desc_type=anywordssubstr&short_desc=subject+header&long_desc_type=anywordssubstr&long_desc=display+scroll&product=MailNews+Core&product=Thunderbird&resolution=---&bug_severity=normal&bug_severity=minor&bug_severity=trivial&bug_severity=enhancement&chfieldto=Now&field0-0-0=longdesc&type0-0-0=anywordssubstr&value0-0-0=long+wide+characters&field1-0-0=short_desc&type1-0-0=nowordssubstr&value1-0-0=char+thread+news+exten+date+list+mime+tab+decod+encod+sort+context+filter+focus+edit

Bug 489609 (wrap subject) would solve the majority of this problem. I'll be working on that bug more this year (there's a patch, but it causes other regressions). The same solution could then be applied to Received: headers and other plain text headers (I've already looked into that). That would solve this bug.
