Fixed error with the floating Layer Control dialog box.  When 2 documents are present in the mainframe, and there is Layer Control dialog, switching the Active document updates the Layer Control correctly, but when the dialog values are modified the displayed images stop updating.

Corrected a defect in  RoiStats3D dialog when measuring the values over ROI and there are several 3D and 4D layers present (calling 3D layer with T>0)
