We can not use software keyboard of Windows XP on "autohide" dialogs
(e.g. Tagging UI, All Tabs Panel.).

When moving focus to software keyboard, dialog will be closed.

This issue is also existing on Linux and Mac. E.g., we cannot change keyboard layout when a autohide popup is opened. But I'm not sure we should mark this bug to all/all. Because we need different patches for each platforms.

I think that this needs big change to XUL panel's autohide rollup mechanism.

Currently we are closing an autohide panel by:

* a mousedown event which fired on outside of the panel on Linux.
* deactivating/activating events of our window on Win32 and Mac.

Maybe, if a panel is autohide mode, we should close it automatically only when our another content which is not a descendant of the panel gets focus.

For fixing this bug, we may need to add a new API to nsIRollupListener. By the API, widget can ask whether the popup widget should be rolled up by the above events.

My idea may be risky changes for some XUL applications, but I believe that this bug is important for accessibility...
