The official demo performs the same in my IE7, Windows Xp system.

In http://www.trirand.com/blog/jqgrid/jqgrid.html

for example:

select “searching (4.0) new” -> “Complex search”

click the “Find records…” button in nav bar

select “Client” instead of “Inv No” at the second line

then the select box next to the “Client” (the operator select box) will be disabled, and anything put in the next text field will return void result after filtering.

Could anyone help me to find a solution? Thanks very much!
