Compatibility mode or not on the browser, I have to get the fingertip
of the pointer at the edge of the + or - circle in the wsw octant to
make it open or close with a mouse click. Anywhere else simply
selects the item.
The arrow keys work as expected.
Any suggestions? Is this another one for a special .html?

Michael,
This is a problem caused by the IE6 override which is drawing the
the cross etc with a canvas instead of using an image created with a
data url which is how the other browsers do it. The stupid thing is that
IE8 and 9 work OK with data urls but the override system is currently
not sufficiently detailed to handle that.
There are three possible solutions. The first and simplest is to set the
Images property of your TreeItems to True and put actual images in
public/images/. The relevant images are still available in
pyjs/library/pyjamas/ui/public/images/.
Another way would be to fix the code in the IE6/mshtml overrides so that
it works properly but I haven't any clear idea what the problem is so
that's a long shot.
Yet another way would be check, in the override file, what version of IE
you are running and if it is IE8 or IE9 execute identical code for
createImage and drawImage to thet in the main TreeItem.py file. However,
I'm hazy about whether access to the navigator object has been implemented.
So I would try the 'Images' property as I described.
I the longer term this is a problem that needs fixing but it impacts on
the contentious issue of whether to drop IE6 support etc.
Regards,
Phil
