3. find a thread with a reply
4. click the reply
5. only that section should reload
6a. try to use scrollwheel
6b. try to focus the textbox at the bottom

Actual Results:  
Mousewheel has no effect.
Textbox will not take focus.

verified with 20030807 build.

[Jesse Ruderman]

Not a dup of bug 212556.  This bug is 100% repro and wasn't fixed by 212556's fix.

[Peter Weatherby]

I can verify this bug is still present in this build:
Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.5b) Gecko/20030817 Mozilla
Firebird/0.6.1+

I can reproduce this problem on the shacknew.com comments 100% of the time. 
Though it does NOT happen on Firebird 0.6

Unlike Peter and Jason, I do see this bug in Firebird 0.6.  I also see this in
nightlies of both Firebird and Seamonkey.

In 0.6, clicking in an empty spot restores scrolling (but seems to make  bug
212556 more likely to happen on an app switch).  In my 08/16 nightly, clicking
in an empty spot does not restore scorlling.

my mistake it does happen in Firebird 0.6, was thinking of Mozilla 1.4.

Works for me, using:

Works as in you still see the bug?  The bug still exists.
Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.7.6) Gecko/20050223
Firefox/1.0.1

Again, the idea is to click a reply and then try to scroll.  You can not.  You
have to click back on the page in a blank area for action to restore.

Yes, the bug exists in 1.7 builds, but not anymore in trunk, 1.8b builds, as far
as I can tell.

Comment 15

[Martijn Wargers (dead)]

Forgot to tell, you can get and try a 1.8b trunk build here:

This does indeed seem to be fixed in Gecko 1.8.  Tested with:
Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.8.0.1) Gecko/20060124
Firefox/1.5.0.1

Marking WORKSFORME.
