Aaron, sorry to point fingers.   Any idea what's going on, here?

Tweaking summary. It's not just netscape.com, I've seen it on other sites too -
like Mozillazine.

if tweaking the summary, please consider my summary for bug 250191 (btw:
as you can see from the bug number, this one is the dup ;-) )

this bug is absolutely independent of the site viewed - it occurs on ANY
site. in fact, it is even unrelated to web browsing. it is impossible to
change focus in ANY mozilla window to ANY window element (e.g. also in the
preferences window, the bookmark manager etc.) and also impossible to
select ANY text in ANY mozilla window, not just in web-forms.

i'm not too much into mozilla's internal development structure, but i think this
bug belongs to "event handling" rather than "layout: form controls".

Actually, that's not true.  I can use my mouse to move the selection point here
on b.m.o itself - I'm doing so as I type this message...

well, i cannot. i am using build 2004070618 on linux i686. are you sure we are
observing the same bug or should bug 250191 be reopened?

I'm using 7/11-08 under Windows XP.  It may be that placing the selection point
has more of a problem under Linux than under Windows.  Or it could be two
different bugs with similar symptoms - it's hard to say.

Please don't reopen any bugs if other people using later builds aren't
experiencing the same problem, unless you try the later build.

I believe the textarea's with problems have a tabindex set.

Attachment: testcase exhibiting source of the problem

the bug is caused by the "tabindex" attribute of the textarea. maybe related to
bug 171366.

A future fix will be dependent on the GetNextTabbable() rewrite in bug 250006,
and would make use of IsFocusable()
