I have a subform on a form (they are linked) and after the end user enters data the focus moves to another subform in which the end user enters more data. After the subform the end user enters data directly onto the form and the focus moves through several other controls & then starts again with the tab order of the form. However the cursor will not re-enter the first subform mentioned. The end user cannot even use the mouse to set focus on the form. Any ideas - (my other subform allows the focus to re-enter).
