    is because there is no "then" in there?

    ive had issues with them placed in the wrong spot 


    msg = wait(0, screen.GetMessagePort())
             if msg.isScreenClosed() then
                    print "Screen closed"
                    exit while
                else if msg.isButtonPressed()


    or should the "then " be with the elseif msg.isButtonPressed() ?

    The "then" of an if statement is optional, so that has no bearing. I was referring to the msg variable holding an invalid values, so something like this may be required:


    msg = wait(0, screen.GetMessagePort())
    if msg<>invalid then
        if msg.isScreenClosed() then
            print "Screen closed"
            exit while
        else if msg.isButtonPressed() 
            ... do something ...
        end if
    end if

    We have an open bug we can easily reproduce by hitting the Home button on a script that causes a wait() with a timeout of zero to return an invalid message. We consider this a bug on our part and will fix it.

    Do you have another scenario that causes invalid to be returned from a wait() with a timeout of zero??
