Scrollbar is stuck and unusable

Scrollbar should still be able to move and function

Was tested using the default theme.

I think this is probably the same as bug 214621.
Admittedly bug 214621 is not very clear for anyone having a quick search through
and should probably be deleted/closed and replaced (perhaps by this bug).

I'm not sure about comment #1, but I've seen this bug.

To reproduce, make sure cookies are set to ask for confirmation, then load a
page that is longer than one screen height and that will ask to set a cookie.
While the page is loading grab the scroll bar and begin scrolling. If you happen
to be scrolling when the cookie dialogue box pops up, after you accept/reject
the cookie, you won't be able to drag the scroll bar, although clicking
above/below it will work as will the up/down arrows.

Yeah, I've seen this too, I can reproduce on build 2003-08-29-04 on Windows
2000, but I've seen this for a couple of weeks, though for a while I couldn't
pare it down to a simple testcase.

If a modal dialog from another application comes up, once you return to the
child Moz window, the scrollbar stops responding to click events, but it's just
the bar.

What still works:

1) Mousewheel
2) Up/down buttons on the keyboard
3) Page up/page down buttons on the keyboard
4) The scrollbar's up/down chrome buttons.

Brian, do you have any cycles to have a look at this?

For me the mousewheel was also disabled whenever the bar was.
