271681 - Scrollbars used with cursor keys leave a sizeable gap in scrollbar base.

Status: NEW

(SeaMonkey :: Composer, defect)

Description

[Stephen Donner [:stephend] Not actively reading bugmail]

Build ID: 2004-11-24-05, Windows XP Seamonkey trunk.

Not sure when this regressed yet, but I'll go back and look.

Steps:

1.  With enough hard return to have a scrollbar in Composer, use the cursor keys
to move up and down the document.
2.  Once you reach the top, not the position of the dragbar in relation to its
'resting place'.

Expected Results:

Scrollbar completely touches its base.

Actual Results:

Scrollbar leaves a sizeable gap.

Note: Page Up/Page Down are fine, it's only the cursor keys that are the problem
here.  Manually scrolling/grabbing with the mouse is fine, too.

Navigating using the cursor to the beginning of the document only goes up to the first line of the document.  The padding stays offscreen unless you use the scrollbar.  I suppose this behavior could be changed, but I'm not sure it would be better to have a little extra jump at the beginning and end of the document.

I guess another possibility would be to get rid of the extra padding in Composer's edit mode; that would more likely lead to problems with complex, though.

BTW, I build Seamonkey because the UI isn't changing all the time.

Can you reproduce with SeaMonkey v1.1.9 ?
