I tried this code in my browser and it didn't pop up with the tooltip text like it would if the object was an <INPUT type="text">.
<OPTION title="OptionTitle1">1 </OPTION>
<OPTION title="OptionTitle2">2 </OPTION>
<OPTION title="OptionTitle3">3 </OPTION>
<OPTION title="OptionTitle4">4 </OPTION>
Any suggestions? I am testing with IE6 and having tried using any other browsers to view it, so it might be IE.
