Pick point is off

I loaded up Intellicad onto yet a second computer for occasional use.
Found something bad and wanted to correct it the other day.


Seems in this one computer the cursor with the little box is not
accurate. Whenever I center the little box over a line, instead some
line underneath the arrow will get picked for alteration. I have tried
it a few ways now, but it refuses to accept a line within the confines
of that little box. It will however pick up one a bit away, usually
under the arrow of the cursor.


How can I get the sensing point to readjust it self back to the box?
