Tony,

If I set the grid resizable, when I open a dialog form, such as search, edit or view a row, I found the grid's resize icon at the right-bottom corner is still display over the dialog form and it can work. I think it's a bug. I visited your demo page and it's the same. You can repleat the problem in your demo page: New in version 3.6/Resizing Grid. Just click the search icon and drag the search form to cover the resize icon, you will find it.

regards
