REALLY close stack - no, really

[John Rule]

Does this feature actually benefit anyone? In all of the years I have used
MC or RR I have been fighting this 'Purge' annoyance (and I have lost some
work because of it). I now just make sure that the 'Destroy' attributes are
set (destroy window and destroy stack)...this works 'mostly', but not
always. I wish it would just be taken out of the engine itself....when I
close a window, I am closing it! If I want to keep it in memory, I will
'hide' it myself.
