Dear all,
I am trying to use the function "impoint" to create user draggable points where some calculation is based upon on an GUI.  However, I found that with a large image, the selection of point is not very responsive, with the first left click end up dragging the point instead of setting it initially.

e.g.

test = zeros(3000,3000);
figure; imshow(test, []);
pt    = impoint;

Is it an expected behavior, or is there any workaround for it?
Thanks,
Abe
