particle analysis within region of interest

This should be simple but somehow I can't get it to work. I want to count particles in a specific region of interest. I have:
Thresholded the image (using, threshold or color threshold-the particle analysis works correctly on the thresholded image)
But when I try to count particles in a subregion, either by using the ROI manager or "selection" "specify", I still get the count that corresponds to ALL the particles in the image.
At the same time, if I use the ROI manager and then the "measure" command, the measurements correspond to the ROI's that I've defined.
Does anyone have a suggestion?  Thanks so much.
