We experienced some issues with the new firefox 3.6 using controls 9.2

so we upgraded to 10.1 and the latest service release.  Our past issues went away but now there is a new one. Whenever you click to edit a cell the grid jumps.  this was a past problem and the following code use to work

<ClientSideEvents BeforeRowUpdateHandler="CancelP"  />

     function CancelP() {


         igtbl_cancelPostBack('UltraWebGrid1');

     }

but its not working anymore. but the grid seems to behave properly in IE8. so it seems to be some combination of Firefox 3.6 with Infragistics 10.1
