>Hello Chris,
>thank you for your reply and sorry for my late reply to you. I will definitely take your advice in consideration. What we are actually using right now is changing main menu pads according to chosen package. The pads for every package are the same, what different is a popup. Everything works pretty well so far. The only little problem we have is when menu changed you can see very pad when they appear on the menu, one by one. The _SCREEN.LOCKSCREEN = .T. and then .F. doesn't work since it works only for forms. Do you know by any chance the way to lock the main menu to prevent this behavior?

If you want to change pads based on what is installed, you might look into the Object Factory and having it create the different menu popups. I've never seen any repainting menu effects, it sounds like this is a machine speed issue. What kind of computer are you using?
