I am using the mouse up event in a shape to resize two grids (one on yhe top of the grid and one on the bottom). When the user clicks and drags the shape the grids will follow in whichever direction and resize as needed to stay within the container they reside in. However the nYcoord is not always accurate to where the mouse up is fired. Is there a conflict with the coordinate's in the container as compared to the form. Or might there be another method to do this someone wants to share?
