This applies to ViewPart sashes as well as common use of the Sash widget.
If a child of one of the sash's children (assumedly a composite) is disabled via setEnabled(false), the sash will not be able to shrink its child.  The sash bar then "breaks" by following the mouse cursor even after the button is release from dragging.

Reproducible: Always

Steps to Reproduce:
1.Use provided sample project
2.If not using the sample project,
Set up 2 views side by side.
In the second view use this code:
Composite main = new Composite(parent, SWT.NONE);
	   main.setLayout(new GridLayout(1,true));
	   
	   Composite stretcher = new Composite(main, SWT.BORDER);
	   stretcher.setLayoutData(new GridData(SWT.FILL,SWT.FILL,true,true));
	   stretcher.setLayout(new GridLayout(1,true));
//	   stretcher.setEnabled(false);
	   
	   Label lbl = new Label(stretcher, SWT.NONE);
	   lbl.setText("Drag view sash over this disabled label and the sash WILL NOT work");
	   lbl.setLayoutData(new GridData(SWT.FILL,SWT.FILL, true,false));
	   lbl.setEnabled(false);
	   
	   Text ctrl = new Text(stretcher, SWT.NONE);
	   ctrl.setText("Drag view sash over this text ctrl and the sash WILL work");
	   ctrl.setLayoutData(new GridData(SWT.FILL,SWT.FILL, true,false));
	   
	   ctrl = new Text(stretcher, SWT.NONE);
      ctrl.setText("Drag view sash over this text ctrl and the sash WILL work");
      ctrl.setLayoutData(new GridData(SWT.FILL,SWT.FILL, true,false));
      
      ctrl = new Text(stretcher, SWT.NONE);
      ctrl.setText("Drag view sash over this disabled text ctrl and the sash WILL_NOT work");
      ctrl.setLayoutData(new GridData(SWT.FILL,SWT.FILL, true,true));
      ctrl.setEnabled(false);

3. Run and try to shrink the view by dragging over a disabled control.
