[Evolution] How to handle the original window when I do a REPLY

[Bill Chmura <bill explosivo com>]

This is a dumb question - but read on anyway:

I could swear there was a setting in Evolution that basically set what
to do with a mail message when I replied to it.  Basically to close the
original window, leave it open etc...

I cannot, however find this.  I have looked and looked and cant find
anything.

I am running 1.4.5

Thanks
