Happens in Win98SE as well, using Phoenix 2003040908.  Seems to occur whether
the "Show window contents when dragging" option is on or off.

For clarity (it took me a while to figure out what was meant), step 3. in
comment 0 means "resize window vertically to increase its height by dragging the
bottom edge of the window down."  (It *is* hard to describe...)

Another method of reproducing doesn't require a vertical resize:

1. Put browser into a window (say no more than 2/3 of the desktop in size).
2. Scroll to bottom of page.
3. Maximize window.

This bug is just like what I saw that prevented me from checking in the patch on
bug 156547.  Hopefully I'll be able to check that in once this is fixed, if it
even does anything anymore.

Has this anything to do with bug 201300?

also occurs under linux (trunk 20030411)

Attachment: straightforward fix

The old code wasn't notifying obsevers when 'curpos' was constrained. That was
OK because the maxpos attribute change was doing enough. Now it isn't.
