[news.eclipse.platform.swt] Windows fires SelectionEvent on tree.setSele

[Fabian Zeindl <fabian@xxxxxxxxxxxxxxxxxxxxxx>]

Hi,
 for some unknown reason Win32 fires a SelectionEvent when I do 
tree.setSelection(TreeItem item) where gnu/linux doesn't fire one.
Is there a reason for this behaviour? Funnily enough, when I change the 
code to be simpler, Windows doesn't fire an event on setSelection.
Is this an SWT-Bug?

thanks in advance
