jQuery Grid Plugin - jqGrid

Hi all

I hope this hasn't been dealt with before - if so, my apologies.

I am not sure, either , whether this should be a help request or a bug report.

Site works fine in FF.

Page loads jquery-1.4.4.min.js

Then a couple of my own js files

Then loads src/grid.loader.js which has all modules set to true

The first time the page loads in IE 7 there are 2 script errors both the same:

'Object doesn't support this property or method'

The files are grid.inlineedit.js and grid.formedit.js

and the line is the same in each case $.jgrid.extend

If I refresh the page the error does not repeat.

Anybody with an idea why this happens please?

With thanks

Mike Jones
