Ivan, could you look at it please? Its probably in Term.

I can reproduce it the same way as Jiri.
Comment 3 ivan 2001-09-27 22:15:24 UTC
I can't reproduce it.
Can you please specify
- how big is the selection (one word, line, multiple lines etc)
- in what direction you resized.
Comment 4 Jiri Skrivanek 2001-10-01 09:40:31 UTC
I hoped it has been clearly described but once more:

- select ALL lines (including empty ones) in the Output window (whole
area is selected)
- change height of the Output window to be smaller (drag top border of
the window down)
- and see exceptions
Comment 5 akemr 2001-10-01 10:55:59 UTC
This bug appears, when you resize window (e.g. vertically) to be 
smaller than selected area.
Comment 6 ivan 2001-10-02 04:58:58 UTC
Got it.
It happens when you have less text than the window height.
This usually happens with a freshly cleared term into which
only a few lines have been written.
Then if you select everything things go bad.
Comment 7 Lukas Hasik 2001-10-05 11:29:48 UTC
Note: sometimes when OW is resized the selection is lost... And you
have to select it again.
Comment 8 Lukas Hasik 2001-10-11 16:26:06 UTC
I think that the NPE is gone.  This bug could be closed as fixed...

Jiri, could you confirm ?

Comment 9 Jiri Skrivanek 2001-10-11 16:36:35 UTC
Verified in build 20011011-1326.

Probably fixed.
Comment 10 Jiri Skrivanek 2001-10-11 16:37:28 UTC
Verified in build 20011011-1326.
