Dialog window does not respond

[Norbert Vischer]

Hello all,

in the following macro, I sometimes cannot change the "hello" string, i.e. the 
dialog has lost focus. The OK button works. I cannot reproduce this problem 
reliably. Activating a different application (e.g. the Finder) and coming back 
helps.
But it possible to blind-fix this problem better?

Best regards,
Norbert



        close("ABC");
        newImage("ABC", "8-bit ramp", 300, 300, 1);
        selectImage("ABC");
        showMessage("Click OK to continue");
        //selectWindow("ImageJ");//does not help
        Dialog.create("My Dialog");
        Dialog.addString("Enter String", "hello");
        Dialog.show;
