Chris,

I see I was looking at an IB_lookupcombo which has both an on
dropdown and on closeup procedure. I increased the width in the
dropdown procedure and decreased it in the closeup procedure and it
worked fine, even when it was in a groupbox. The IB_combobox does not
have a closeup procedure, so after I increased the width in the
dropdown procedure and selected an item, when the box closed the
field was truncated on the right because I couldn't decrease the
width. If you could add a closeup procedure to the combobox, then you
could get it to work (at least with my method).
