lockScreen

set [the] lockScreen to trueOrFalse

The lockScreen property returns or sets whether HyperCard updates the screen when you go to another card. You can use lockScreen to prevent the user from seeing cards as a handler goes to them.

The default setting is false. HyperCard sets lockScreen to false on idle.

Setting lockScreen to true speeds up scripts that go to cards momentarily before returning to the source card. (HyperCard runs faster when it doesn't have to redraw the screen.)
