I do not think jBox would be the issue. All jBox is doing is sending
the X,Y coordinates of your box back to mapserver. I would guess it
was the database, but that's a guess. What browser are you using? jBox
with Firefox/Mozilla is very slow to instantiate the first time, but
that has nothing to do with the box drawing, it is a Java issue.
