SolidWorks 2011 AutoArrange Drives me Nuts!!

Change a dimension (i.e. Make it Basic) and it automatically moves to some random location (that must make sense to solid works), you move it, click away and it moves back and again and again finally after the fourth time it sticks.. What is this about??? Does anyone know where in the Options or customize you can shut this feature off. Thanks in advance!
