i posted an update to the calendar control.

my question on this, since i cannot obviously adjust a pointer, is how do i set the calendar one year ahead so thhat it can be used to set an expiration date on a program?

the main program uses this calendar control to set an expiration date on a second program..

i attempted to do something like

incr @xhdr.st.wyear but it obviously gpf'd on me....

see this link for the control:
