Changing screen layout slightly changes coordinates, tests fail

If there are internal application methods that you can use to determine the position of the grips, then you could use those to determine start point.  A developer might be able to help if TestComplete has access to the application's internal methods.  You could also do math to determine how far to drag, etc.



Neither of these solutions will help if you're going to do a Picture comparison on the plot though, as the change in layout would cause that to fail.
