366604 - Some Listboxes with scrolling failing to display scrolled-in items

Status: RESOLVED DUPLICATE of bug 365234

(Thunderbird :: Mail Window Front End, defect)

Description

[Mike Cowperthwaite]

TB 2b1-0108, 3a1-0108.  I have a 3a1-1206 build that works, a 3a1-1210 build that does not.

I see this problem in two places: Filter Rules dialog when there are a large number of criteria, and profile selector on startup when there are many profiles.  When the dialog in question is opened, it displays the items in the list OK, but any scrolling that occurs brings apparently-empty space into view.  

The invisible items cannot be seen by clicking in the space, but selecting the item next to the empty space and using arrow keys will work.  However, each time one of the items is made visible below, the item scrolled off the top becomes invisible, as seen when scrolling back.

In the Filter Rules dialog, using down arrow from the bottommost item (N-1) will make the next two (N and N+1) visible; and each subsequent arrow to item N will continue to make item N+1 visible, while hiding the items that scroll off the top.

This sounds like bug 365234, but it was fixed on the trunk on 12-31 and on the 1.8 branch yesterday.

Thanks, Gavin -- I looked for dupes but forgot to look at fixed bugs.  And my comment about 3a1-0108 was wrong, I thought I'd seen it that build just yesterday but didn't explicitly retest.
