Hi,
I am using treeview and listview as my user security maintenance. I have prloblem that, the screen doesn'rt refresh smoothly while I re-create the items of listview and add/remove node in treeview. I used to try FORM.LOCKSCREEN= .T. before recreate items and FORM.LOCKSCREEN = .F. after it. However it doesn't work

How to make it work smoothly?

Thank you
