I still have the problem with cut/paste, after heavy use like several hours
it always freezes up. Rather consistent, but I'm using N.Aes.  With light
use it don't happen, it takes a marathon coding session.  I'm using the
build from gokmase's page. I have to kill it twice, then it won't run again
until I reboot.  I figure it has memory leak or runs out of file handles or
something along those lines.
