Hi,
I'm trying to preserve state in a GridPanel. I have taken the GridPanel example and added the following lines:
stateful: true,
stateEvents: ['click'],
stateId: 'example_grid',
To test this I clicked on a column heading pull-down menu, and hid one of the columns. Then I hit refresh, and expected that column to be hidden.
This works fine in Firefox 2 on Mac OS X, Firefox 2 on Windows Vista, but doesn't work in Internet Explorer 7.0.6000 in Windows Vista Business.
A working example is here:

Any help would be gratefully appreciated.
