Odd. We usually use Mozilla as primary browser during development.

I just printed a bunch of problems on Mozilla 1.6 (Mozilla/5.0 
(Macintosh; U; PPC Mac OS X Mach-O; en-US; rv:1.6) Gecko/20040113), 
using LON-CAPA 1.1.99.5. Also, the "Select" buttons worked.

Thinks to try:

* Open new window, type "javascript:" (return) - any messages there?
* Try printing another set
* After doing this, check out the last lines of
/home/httpd/perl/logs/lonnet.log
/etc/httpd/logs/error_log

- anything?

Is that the same problem set?
