Window resizing before open?

[Frank Leahy]

Hi,

I seem to recall a discussion a month or so ago about how to set a 
window's size before it opens -- but I can't find it via Google.

All of my windows want to resize themselves smaller when they open, and 
so I've taken to resetting the height on preOpenStack, and because that 
doesn't always work, in openStack as well.  But this can cause a flash 
as the if the resize happens after it becomes visible.

Can someone enlighten me about the best way to resize a window before 
it becomes visible?

Thanks,
