Hi everyone,
Is anyone with Tiger experiencing erroneous scrolling when combining a
scrollwheel with mouse clicks? I have observed this to happen with both
"lists" and "panes" that have scrollbars, and also in text-edit boxes.
Basically, here are the apparatus and steps to reproduce:
- People using Tiger (e.g. 10.4.3). I am not yet clear on which
hardware or software versions experience the problem, so I would
appreciate any feedback to help me report this to Apple's Radar.
- People with a scroll-wheel mouse (e.g., Mighty Mouse or Windows
mouse) or PowerBook with scrolling trackpad.
- Any application window with multiple scrollable areas (where
"scrollable" includes regions with scrollbars *and* also text boxes
with text that is too long to fit on-screen at once). Some examples:
iCal with a long list of To-Do items; iTunes' "Get Info" window with
long track titles.
0/ Open a programme with multiple scrollable regions or text boxes.
1/ Scroll one such area to its top- or left-most extent. I will refer
to this area as area "A".
2/ Now click into another scrollable area or text box, which I will
call area "B".
3/ Now move the mouse over top of the original area, A, but do not
click on it yet.
4/ Use your scroll wheel or scrolling trackpad to scroll area A to a
new position.
5/ Now click an item or text location within area A.
6/ Observe whether area A has jumped back to its original location and
selected the wrong item (or text location).
If you try this, could you e-mail me off-list? It's possible that this
bug is already widely known, and I don't know how long it's existed.
PS. The point of this bug seems to be that if you scroll an area ("A")
while the text-entry focus is in a different area ("B"), then clicking
into area "A" will cause it to return to the position it had when you
originally swapped the focus to area "B".
