Description settantta 2002-06-12 04:59:06 UTC 
When attempting to scroll by one line using the vertical scrollbar, the page
scrolls continuously to the end of the document, then returns to a position one
line down from the previous position. This also occurs when attempting to scroll
by one screen.
It is most commonly seen in imported Word documents, but I have also observed it
in native Writer documents.
This is readily reproduced. Open a Word document in OO.o 1.0, click on the arrow
on the scroll bar, or click in the scroll bar.
Using the keyboard, Page Up or Page Down, works correctly, as do the cursor
keys. The double arrow (next page) woeks fin also.

A suggestion was that the "Smooth Scrollin" option might be
responsible. Apparently turning it off helped some, but not for me, as
I *never* use smooth scrolling. 

The problem is definitely not restricted to impoted documents, as it
occurs in a brand new untitled doc. (although, maybe... The document I
was creating is based on a template converted from Star Offie 5.2)

On my slow Thinkpad, I have troubles to select more text than visible
on the screen. When I try to do it, the scrolling is slow, and when I
stop holding the mouse button several more pages get selected, because
there seems to be more "draging" in the input event buffer/queue.

I've got the same problem with scrolling using the arrow keys. 
Even if I release the key, the document keeps on scrolling another
minute or so.

Btw. the same bug is in mozilla, so I guess it's not so easy to fix.
When scrolling the writer has to flush the event queue regularly
before processing the next input.

Just in case you're interested. Information on the Mozilla bug is
http://bugzilla.mozilla.org/show_bug.cgi?id=25054

It says:
When using the arrow keys to scroll in the main browser window, if the
keys are pressed too frequently, they will "queue up".  This means
that the window will continue to scroll for a while after you have
finished pressing the arrow key which can be most irritating.

Which is exactly what I'm observing with writer. Btw. contrary to
mozilla, the writer also queues up the "scrollbar down-arrow".

-> Alex: the smooth scrolling is not the one from the mouse settings
but from the OOo options (Tools - Options - {component} - View).
Please check this.
If the problem can be reproduced with 1 particular document, please
upload it.

This may have been a 1.0.0 problem, as I haven't noticed it in 1.0.1
and on. (Must confess I'd forgotten I'd submitted this...). It was
definitely a problem, but only with the scroll bars, and as I said, I
haven't seen the behaviour since I upgraded to 1.0.1. Seems to me that
I should have closed it as FIXED some time back... :(
