Hi David,

a temporary workaround if you have the
latest cvs fo VTK, is to change what the
buttons do:

from /Examples/GUI/Tcl/ImagePlaneWidget.tcl

<snip>

vtkImagePlaneWidget planeWidgetX
  planeWidgetX DisplayTextOn
  planeWidgetX SetInput [v16 GetOutput]
  planeWidgetX SetPlaneOrientationToXAxes
  planeWidgetX SetSliceIndex 32
  planeWidgetX SetPicker picker
  planeWidgetX SetKeyPressActivationValue "x"
  set prop1 [planeWidgetX GetPlaneProperty]
  $prop1 SetColor 1 0 0  
#
# set the left mouse button to do the pushing
#
  planeWidgetX SetLeftButtonAction 1
#
# set the middle mouse button to do the cursoring
#
  planeWidgetX SetMiddleButtonAction 0

<snip>

of course, you could just purchase a 3 button mouse ...
