I looked at this and can not offer a simple explanation, but like I said 
in the howto at
It generally works with setimage(). In the simple example in the howto, 
the map is rendered when jBox is initialized and that's it. Each page 
submit causes the process to happen again. But with setimage(), the jBox 
applet gets initialized, and then setimage() takes control of repainting 
the page. setimage() provides a lower level of control, but requires 
more effort on the part of the application. I do not see a simple way to 
display a busyimage when using the "basic" jBox functionality as jBox 
stands now. I suspect that some modification to jBox would be required.

Regarding the redraw issue. Steve says redraw is no longer used, so I 
will correct the howto.
