Hi,

This JavaScript function:

                        function selectd() {
                           for(var
i=0;i<document.fmain.user.options.length;i++) {
                              if (document.fmain.domain.options[i].value ==
                             
document.fmain.user.options[document.fmain.user.selectedIndex].value) {
                                 document.fmain.domain.selectedIndex=i;
                              }
                           }
                        }
                        function selectu() {
                           for(var
i=0;i<document.fmain.domain.options.length;i++) {
                              if (document.fmain.user.options[i].value ==
                             
document.fmain.domain.options[document.fmain.domain.selectedIndex].value) {
                                 document.fmain.user.selectedIndex=i;
                              }
                           }
                        }

Causes Safari to beachball for around 15 seconds before selecting the correct
domain/username on a 1.5Ghz PowerBook, with 1.25GB or RAM runing Tiger. 

I can't give you a test case as this function is taken from WHM a script that
requires root authentication on a server which naturally I can't put in a bug
report. Basically there is a list of around 600 domains and a list of about 600
usernames, if the user clicks on the username it will search through the list
of domains for the matching domain and vice-versa.

On the latest nightly the beachball spins for around 5-7 seconds, so there has
been some improvement. However both FireFox and Opera select instantly, no
noticable delay what-so-ever.

Andrew
