I have some old code that was automatically generated by an old menu program I must have used at one time. It still works in IE and FF but in Google Chrome, the drop down menu's are separated from the menu titles making navigation very difficult. I only have one java class under my belt so this javascript has been difficult for me to troubleshoot. It appears there is some browser identification happening and I'd like to alter the code that it's defaulting to when it determines it isn't one of the listed browsers (interesting that FF is not listed but the script works fine in FF).

There is another js file that calls this one but I'm thinking this one is the file that is causing Chrome to screw up the menus. I'm just looking for someone to tell me what I should comment out or change to get Chrome working. I realize this is very out of date and don't care to get the browser section updated with current browsers or anything. Thanks for looking.
