Changing the screenRect within a stack

Dear Francis,

Please, stay away from my screen. it is MY screen and NOT yours. You  
simply have no right to change the system settings of my or anyone  
else's computer. Of course, this message isn't only meant for you, but  
for anyone who thinks of changing someone else's screen rect. Please,  
don't do it.

Instead, you should detect the screensize and resize your stack window  
and the objects in it to accommodate the screensize. Never do the  
oppositem don't change the screen rect.

You should also take into account the possibility that the user  
changes the screen resolution while your application is running. For  
this, you can catch the desktopChanged message and adjust the window  
and object sizes again (and indeed, you need to check the  
windowBoundingRect and (working) screenRect(s) too).

Now, if you're really still not convinced, I can tell you there are a  
few command line utilities, but they need to be updated every now and  
then, because they can't cope with the many different screens and  
screen resolutions available these days. I believe it is possible to  
use the terminal or applescript on Mac OS X, but I haven't seen a good  
working solution.

Best regards,
