The mouse scroll wheel doesn't work if the mouse hovers near the bottom of any
HTML page displayed in a browser window.  This bug is independent of the myriad
other focus and form element scroll wheel bugs -- it occurs even on pages with
no form controls and which have been properly focused.

Moving the mouse above the bottom 50 pixels or so in the window reactivates the
scroll wheel; if the mouse moves back near the bottom of the window, the scroll
wheel again doesn't work.

A url or a testcase would be helpful in reproducing this bug. Thanks!

I wrote "any page".  The one you're looking at now is as good a test case as
any. and are two other fine test cases.

Btw, I'm using the classic skin under MacOS 9.2.1, if that matters.

The problem seems to be that although Navigator displays the toolbars at the top
of the window, it seems to think that they are at the bottom for the purposes of
determining valid mouse positions for using the scroll wheel to scroll the
window.  Using the mouse wheel to scroll the window works when the mouse is over
the toolbars (although maybe it shouldn't) and doesn't work (and should) when
the mouse is over the bottom n pixels of the window, where n is the height of
the toolbars.  Collapsing the toolbars decreases the size of the dead area at
the bottom of the window.

The symptoms of this bug have changed a bit recently.  Now the mouse wheel
doesn't work near the bottom of any page (as before), but once it has been used
successfully higher up on the page, it then begins to work near the bottom of
the page as well.  Weird.

To re-trigger the bug, resize the window.  The scroll wheel won't work near the
bottom of the page until it has been used successfully in the middle of the window.

Seems to work ok on Mac OS X but we handle mousewheel scrolling differently
between X and 9.x.
