SWT ExpandBar flickering

[Tomasz Wroniak]

Hello,

I am developing a simple SWT application using ExpandBar. The problem is that the widget is flickering when I'm moving my mouse cursor over it. The same problem seems to occur when I run a sample ExpandBar application from examples at eclipse.org. I've encountered the problem which looked very similar to this one when I was writing a Java2D application and forgot to turn on double buffering. Is it possible that ExpandBar is not double buffered by default? If yes, is it possible to turn it on? (SWT.DOUBLE_BUFFERED passed to cnstructor doesn't seem to do anything noticeable).

Thanks
