Resizable stack on Windows standalone?

[Jon Seymour]

Hi, I'm developing on OS X and creating a standalone to run on  
Windows. So far...remarkable how well it works. But for the life of  
me I cannot figure out why my stack can't be resized in Windows.  
There simply isn't a place to drag. I'm sure the stack is set to  
"resizable" and I even set the property in a script when it opens.  
I've looked at many Windows apps and find the same drag icon in the  
lower right that I'm expecting Rev to put in there for me. But no.  
Help!?!

Thanks, Jon
