i dont know if this will work or evne if this is what u want but try this.
find this (Line 447 on my default.asp):
Response.Write "<a href=""" & ScriptName & "?" & HideForumCat & "=N"">" & getCurrentIcon(strIconPlus,"Expand This Category","") & "</a>"
then replace it with somthign like this:
Response.Write "<a href=""" & ScriptName & "?" & HideForumCat & "=N"" onMouseOver=""document.all.music.src='YourWavHere.wav'"">" & getCurrentIcon(strIconPlus,"Expand This Category","") & "</a>"
then find this (a few lines down):
Response.Write "<a href=""" & ScriptName & "?" & HideForumCat & "=Y"">" & getCurrentIcon(strIconMinus,"Collapse This Category","") & "</a>"
end if
then add this under the "end if" part:
Response.Write "<bgsound src=""#"" id=""music"" loop=""1"" autostart="""true""">"
i dont know if this will work but i got this code from [url=http://javascript.internet.com/user-details/click-sound.html]Here[/url]
hope this helps
