In the list control double click property change, it would be helpful to have an option of "none" so that you can revert back to no double click action taking place. Now, if i want to try a double click action and then change my mind, it seems i have to rcreate the control all over again to reset the double click action to the default.
That has been reported once already be me.
As a workaround I created a simple NULL Device called NULL and I point all of these 'change my mind' things to that NULL device. It just doesn't do anything, but it prevents me from having to create a new control.
