For example, my screen is 1920 x 1080. When PT is somewhere to the right of the initial visible window, I'm getting X coordinates to a tune of 8,000 and so forth. How can I obtain the correct X, Y, HPOS, VPOS when dealing with a non-nil truncate-lines situation? [Everything works as expected when truncate-lines is nil.] Thanks, Keith
