Try suspending the program, ACTI SCREEN, and then open BROWSE windows for all four tables. Select Table1 and navigate through it. If Table3 does not update properly then you probably have a problem with the way the relations were set.

If the BROWSE windows show properly, then my guess is that you have a problem with Refreshing the grids on the form. Make sure the AfterRowColumnChange method in Grid1 fires a refresh of all the grids. I would probably do that as the last step in the form's Init method as well.
