jQuery Grid Plugin - jqGrid

Hi, 

I'm using the amazing jqgrid 4.4.0 but just noticed a weird little problem in Chrome.  If I display the Add Record form input dialog and then cancel out of it, somehow horizontal scrollbars appear on the main grid once the dialog was closed.  I'm not doing anything strange as far as I know.  The main grid has one subgrid.  

Actually this only happens for the Add Record grid on the subgrid.  Opening a dialog for the main grid and cancelling out does not add the unecessary horizontal scrollbars, just the add dialog for the subgrid.  Both grid and subgrid are fixed width columns in the colModel.

thanks for any help with this cosmetic issue. 🙂
