Stack in runtime...

[Gilberto Cuba Ricardo]

Hello colleagues,

I'm a new in the use of the Revolution and recently I began their study.
Today studying many of their things, has been that when I make a stack in
runtime with the invisible property, then when I will show the stack, 
doesn't
make it, and neither closes it in case I doesn't put the invisible property.

This is my code the which they can check to see in what I have made a 
mistake.

In the script button:

on mouseUp numberButton
    if numberButton = 1 then
        create invisible stack "MyStack"
        set the visible of stack "MyStack" to true
        wait 10 seconds
        close the defaultStack
        delete stack "MyStack"
    end if
end mouseUp

Best regards,

Gilberto Cuba
