Create a new image (8-bit, 400x400)

Activate the multi-point ROI tool.

Click on the image to add 2 or more points and they are placed in the corrrect position.

Clear the points.

Zoom in so that the window shows only part of the image.

Click on the image. The first point is added correctly. The subsequent points are not created in the correct location. 

Note that points can be moved to the correct location by dragging.

So the click-to-create function maps screen coordinates to the wrong place on the image. Dragging a points maps coordinates correctly.

The latest ImageJ daily build (1.50h32) fixes a 1.50d regression that caused
the multi-point tool to not correctly place points on zoomed images.
