Trouble with ImagePlus.setSlice() method in ImageJ ver 1.37j

[Soft Aliance]

Hi all,
I want to update the image window inside a loop. Imageplus.setSlice(int
nslice) method is not doing that. In the sense I could see the scrollbar at
the bottom is moving. But the image canvas is not getting updated. It gets
updated only at the end of the loop.  I have tried giving a delay of one
second and neither the status bar on the top nor the image canvas gets
updated.
my code is something similar to

ImagePlus imp = WindowManager.getCurrentImage();
for(int CurSlice = 0 ; CurSlice <  imp.getStackSize() ; CurSlice ++)
{
         imp.setSlice(CurSlice);
        // IJ.wait(1000);  //Commenting or uncommenting this line did not
have any effect
}
Infact MultiMeasure plugin when I use it to measure in stacks same problem
exists. The image window is not updated while the scrollbar keeps moving.

You probably want to call "updateDisplay()" after this:
