Warning: Unresponsive script

Warning: Unresponsive script


I am using a simple ASP.Net Grid and using the .hover() function to highlight the Table Rows on mouse over.

$(
 "table.scrollTable td" ).hover(
           function () {$( this ).parent( "tr" ).addClass( 'rowSelect' ); },
           function () { $( this ).parent( "tr" ).removeClass( 'rowSelect' );
});

Its works fine when the records are less.. but when the records go above 150 rows it hangs the browser and gives a unresponsive script error saying

"A script on this page may be busy, or it may have stopped responding. You can stop the script now, open the script in the debugger, or let the script continue"

http://path....../jquery-1.3.2.min.js:12

pls see attachment for the exact error popup.

This behaviour was there in the Firefox ver. 3. which the client is using.
I have upgraded to ver. 3.5, but i still have a performance issue cuz of this as the screen loads up very slow. if i remove the script it loads much faster.

I dont seem to understand if this is a Jquery or a Firefox issue. This issue also comes up randomly if the records are more than 200 in Internet Explorer 7 and 8.

Has any one come up with such an issue... any solutions for this one ???
