(code Included) And IE Conflicts - Parent / Child Node Conflicts

For a widget I made, I have a dropdown select menu. It is constrained to a very small width and IE does not auto expand on click. I wrote a simple javascript to handle this but I run into two problems. The onmouseout function is fired when I click into a child node, and the onmousedown of the <option> tags doesn't work in IE. The code works fine in all other browsers.

var wid;
var campaign_i = 0;
function campaignWidget_capture(myID){
wid=document.getElementById(myID).style.width;
campaign_i++;
}
function campaignWidget_SubDes(myID,state){
if(state==0){
[Code]...
