systray icon questions

[Kirill K. Smirnov]

Hi, all!
I was playing around systray icons in various modes
1)
"allow the window manager to control the windows"="on"
"emulate a virtual desktop"="off"

As result, systray icon is OK.

2) In other combination of these parameters, the icon is drawn with window 
title.

I've tried to investigate the problem and created the patch (attached).
But it solves the problem only in non-desktop modes.
In desktop modes only window title is drawn.

So the questions:
1) Does systray icon helper window really need to be created with WS_CAPTION 
style?
2) What does "managed" mode mean?
3) When I select "desktop" mode, should we disable the "managed" checkbox?

Thanks in advance,
