I see it on the bottom links using build 2005-06-03-06, Windows XP Seamonkey
trunk.  I'd like to get a minimized testcase before fully confirming it, though.

Reproducible with Mozilla 1.8b2/20050602 and Deer Park a1, but WFM with Mozilla
1.8b1.

Doesn't happen with 2005-03-29 build, happens with 2005-03-30 build.
I think it is a regression from fixing bug 255863.

To reproduce this in the testcase, click precisely on the text of the links
When I click for the first time on the link in the testcase, I see the
'not-allowed' cursor, which you also get when a dragging operation is performed.

I can't reproduce. Could this be Windows only?

I can still see it with this build. So, yeah, maybe it's a Windows only issue.

Ere, another windows mouse event handling issue maybe

Comment 11

[Ere Maijala (slow)]

Quickly looking mouse messages seem to be ok but something else happens when the
left button down message is dispatched (or focus is changed).

Comment 12

[Ere Maijala (slow)]

Also this is a a cross-platform problem. The test case just requires that the
window is narrow enough that the menu bar at the bottom overflows to the left of
the visible area. What I can say is that something weird happens when an element
then gets the focus (when the mouse left button down event is fired). Seems to
me that the element jumps causing the mouse to "move". Anyway, this is out of my
scope.

A small error in the mouse synthesis code ... aEvent->point is relative to the
widget origin, which does not necessarily coincide with baseView's origin, so
we need to correct for that.
