That's an interesting idea. I wish it were just a simple display issue. The image being displayed is also being edited (cropped, resized, annotated with labels and arrows)... all in VFP with the help of an image-processing DLL. So I need to be able to drag-drop onto the image and also know just where on the image (which may be scrolled H or V) the object was dropped. Do you know if the "viewport" coordinates for a scrolled webbrowser control are accessible? Can it pass drag-drop, mousedown, mouseup, mousemove events back to vfp?

>>I've found that when using scrollbars to display a large object (image) in a viewport, there seem to be some undocumented maximums imposed. For example, the largest image height I can use is about 2400 pixels. Anything on an image taller than that (assuming image TOP=1 on form) is clipped from the bottom of the image with no warnings or error messages.
