onKeyCtrlEnter not firing if cell is being edited

In a grid (2.5.1) If I am editing a cell and hit Ctrl-Enter onKeyCtrlEnter isn't firing. How can I get this key to fire reliably no matter what state the grid is in?

I misspoke, we are using 2.5.0, any thoughts on why this is happening?

Nobody?

Sorry, cannot reproduce this - the event fires ok, both in 2.5.0 and 2.5.2 (checked in IE7, FF3, Safari 3.1).

grid.onKeyCtrlEnter = function(){alert(1)};
