I have a Main form with a subform1 which has a nested subform2. The main form has two unbound combo boxes and a bound text box, these forms are linked and well synchronized and movement between controls from form to subforms was fine until I added a command button on the first subform to open another form. When I open the form I retrieve a record in the main form and enter new records in the two subforms, up to this point everything is fine, but when I retrieve a new record in the main form the cursor jumps from the combo box to the last control in the second subform. I don't understand why adding the command button changed the behavior of focus between the forms and controls. I have tried several ways of setting the focus to a control in the first subform without any results. I'll appreciate any suggestions to resolve this problem.
