Hi,

there are some things in qooxdoo that I noticed long time ago and they
still appears. All can be reproduced using current demobrowser.

1. Open some demo where is scrollbar (for example this
http://demo.qooxdoo.org/current/demobrowser/#table~Table.html), push
mouse button down at one of scroll-pane and go outside the browser
window. When you will be outside the window, you can release mouse
button. When you go pack to browser window, the scrollpane still moves
(qooxdoo not noticed that mouse is not in down state).

2. This is probably related to #1, when you press mouse button on
something (for example window caption, etc) and move outside browser
window, it stops moving. I thing it should move but coordinates should
be saturated. There is also same problem as in #1 (Window still moves
when mouse button was released).

3. Open all items in left treebox (we are still in demobrowser) then
go to the split pane (between tree and demos). There is noticeable
time between mouse cursor is changed to "horizontal-split" one
(cpu=100%) and when you go out of this pane (go in left direction to
near scrollbar) there is also noticeable time (see cpu meter) and
mouse cursor is not changed back, you must do another move. Noticeable
delay is for me 2 seconds (I'm have CQuad 2.4GHz). I think that there
is something very ineffective in mouse cursor handling or mouse
handling.

Are these things known?

I'm using Firefox 3.5 under 64-bit Gentoo Linux. I think this can be
also reproduced under Windows as well (I'm sure about #3).

Cheers
