I have a vba app that uses the acfocus control. However it is used in machines that have ACAD 2002 and other ones that have ACAD 2004. Is it necessary to change acfocusctrl.dll by acfocusctrl16.dll in all forms when using ACAD 2004 ? What is the best way for apps that run in different versions of ACAD ? Thanks, Tacito Fieker
