Comment 13 Miroslav Lichvar 2012-11-08 07:57:32 UTC
Can you please update to xterm-286-1.fc17 and see if the problem persist?

Comment 14 Thomas E. Dickey 2012-11-09 21:15:43 UTC
I don't think that will change (it's recent but no rework was done).

In a quick check here, I don't see it breaking.  However the new
code (which is being exercised) could break if the event did not
pass the xterm-widget but rather some other widget.  In other places
I guarded against that by calling getXtermWidget() rather than casting
the value.

The report does not show the X resource settings; given the traceback
it seems that the alternateScroll resource would be set.  If the widget
is not really xterm, then the associated screen pointer would be invalid
(whether or not the alternateScroll resource was set).

It would be nice to have the X resource settings (and some clue of the
user's interactions with xterm) to see which path led to this.

Comment 15 Thomas E. Dickey 2012-11-19 10:00:27 UTC
However, adding a guard inside AlternateScroll() would not change
xterm's behavior since there is already one in AmountToScroll()
which is used in each of the callers.  I don't think there is
enough information here for me to reproduce the problem.

Comment 16 Mike Lindner 2013-02-26 18:07:39 UTC
I can reproduce the problem at will by placing the mouse over the scroll bar and scrolling up using the scroll wheel. Works every time. Note that scrolling using the mouse wheel in the text area works fine, only scrolling up using the scroll wheel in the scroll bar produces the problem.

Comment 17 Thomas E. Dickey 2013-02-26 20:39:07 UTC
The difference (if any) between the two is that the action within
the scrollback is added using XtAugmentTranslations.  A long time
ago (say more than ten years ago) there were some systems which
didn't work well with that (seems they had some tablesize limit?).

But I'm not seeing the same problem with the Fedora package for
xterm in Fedora18 - so I'm still stuck.  Clicking up/down and
dragging all work - here.

Comment 18 Mike Lindner 2013-02-26 22:49:19 UTC
Don't click or drag. Both of those actions work for me too. Just place the mouse pointer over the scrollbar and use the scrollwheel. If you want i can post details of my hardware configuration...

Comment 19 Thomas E. Dickey 2013-02-26 23:29:51 UTC
I did that, too.  But Matthieu Herrb's followup to me indicating
your additional traceback, etc, got me to notice the attachment
in comment #4 and realize that getXtermWidget() is needed in this

Thanks, Thomas.
