Hi

Did there happen any changes in SashForm from M6 to M7 that one needs to
be aware of? The reason I ask is because with M7 Azureus stopped working
(it still does with M6).

I'm not entirely sure the problem is in SashForm, it's just my
impression from the stack trace below.

It looks like someone is using GridData for a FillLayout.

cast to org.eclipse.swt.layout.FillData

I had similiar problems after updating to newer SWT versions for cases where
is was wrongly using a GridData in a FillLayout. Make sure that in any case
the Layout of the Parent matches the LayoutData of all Childs.
