ListGrid slowly with Chrome

[manu99]

Hello,

I use smartgwt 2.4 and i have a problem with google Chrome.

Chrome (8 th & 10) 2 features a ListGrid are extremely slow:
1. adding a record ListGrid
2. Editing cell in the new record (change focus)
I don't have this problem with other browsers IE 8 and Firefox 3.6

{_1=isc.FormItem.$763(this)}else{try{_1=isc.FormItem.$763(this)}catch(e)
