<DIV><FONT size=2 face=Arial>Yes, I am using Win XP. I have tried the
rubber band redraw code from vtkInteractorStyleRubberBandPick and
it appears much quicker. I just need to work out how to show the band on
the background.</FONT></DIV>

this under XP by any chance? What action are you doing (zoom window,
area picker, etc?) We've had this problem under XP with the zoom window
support but not with the area picker. We ended up tweaking the zoom
window mode to use the same commands for drawing the rectangle as the area
picker did.<o:p></o:p></SPAN></P>

rubber band as the mouse moves flashes and is slow (VTK 5.4.2, MFC,

improve the speed by creating "tmpPixelArray" outside of the mouse move
handler but it has little effect. As the window size is reduced, the movement
becomes smoother but unfortunately this is not a solution
