aaaawww, just when i thought i was done with this form .....

?? any idea what's causing this ??

just made a form that has 3 container objects on it. two of
those containers (MEDS & PROC) are nearly identical. they both contain a
listbox, a few buttons, and a few textboxes. in the interactive
change event for the listbox, i scatter the selected record
into a named object and refresh to display (control sources for textboxes
are fields in the named object).

when i make visible the PROC container, i can click on different
items in the listbox forever, and it displays as it should continues to work as normal.

when i bring up the MEDS container, i can click on different
items in the listbox maybe 2 or 3 times, and it works ok. after
2 or 3 times, the listbox IAC event quits responding to the mouse click.

IAC will however fire using the up & down arrow keys.
and i can every time click on the 'close' button to hide that container
and return to the previous container.
