Summary0002562: Hotlist and global history redraw issues
DescriptionIn some circumstances the hotlist and global history windows are not redrawn correctly. The bottom item disappears when a higher item is expanded. When two items are contracted, the last item is not erased.
Steps To ReproduceOpen a hotlist or global history window with blank space below the bottom item.

1) Expand an item other than the bottom one, and observe that the bottom item disappears. Contract the expanded item, and observe the bottom item reappear.

2) Expand two items, then contract them. Observe that the bottom item appears in its correct position, but also in its last position prior to the contraction.

In both cases, dragging another window over the area in question causes it to be correctly redrawn.
Additional InformationObserved in CI #4213 and a few versions before it. It probably crept in with the search feature.
TagsNo tags attached.

Screen shots taken with CI #4326 on RISC OS:

screen1.jpg: Hotlist
screen2.jpg: Hotlist with one section expanded - note the bottom item has disappeared
screen3.jpg: Hotlist with two sections expanded
screen4.jpg: One section contracted - note the bottom line appears twice
screen5.jpg: as screen4 but after dragging another window over part of the last line, in order to force a redraw.

I kind of expect it to be RO-specific. It looks like an off-by-one error when calculating how many rows to render.
