Subject	[platform-swt-dev] XP Scrollbars becomes temporaly visible...

Hi, 
I'm experiencing this funny, strange, but buggy situation:

I use a Canvas widget with H_SCROLL and V_SCROLL styles, and hidde both
scroll bars using getVerticalBar().setVisible(false)
(this is done to support mouse wheel, and scrollbar user viewing and gesturing
are other widgets ). 
Sometimes in my code I call getVerticalBar().setSelection( value ), otherwise
mouse wheel scroll from bad value 

On win32 if I set my desktop style to "Windows classic Style",
I never see the hidden scroll bar as I expect (good!),
but if I set my desktop style to "Windows XP style", each time
getVerticalBar().setSelection() is called the hidden scroll bar s
are drawn, and "removed" by next Canvas's paint event.

Does any body have already seen this behavior ? 
Is it a SWT problem or XP one, how I can correct this  ?

Thanks for your help. 

Arnaud.
