Thank you for the reply!
Yes, document-based.
However, not sure if it is an issue, but I have my own subclassed window
controller. The docs also say that the default for "shouldCascadeWindows"
is YES. I tried to set it to YES in "setShouldCascadeWindows:", without
luck.
I look at the EnhancedDataBurn example but it uses the origin of already
shown window, which is slightly different than my case, I believe.
