Bug 178325 ControlExample Tree tab forgets "Moveable Columns" attribute
3.3M6 test build - run the control example, go to the Tree tab - select all of the checkboxes in the "Other" group - change the Tree's style to SWT.MULTI - note that all of the checkboxes in the "Other" group except for "Moveable Columns" stay checked - on the Table tab this item stays checked with these steps
