I'm being punished for it now by having to reinstall everything on the
machine from the opsys upwards. I guess it got jealous too and trashed itself.

There's some oddity going on here -- no doubt explained in the core manual
(which I didn't have backed up, and haven't yet redownloaded). The
initialization
code gets executed and then stripped out as part of building
the object. The result of making an object is a series of assignments only,
as this example shows:
myobj1: make object! [
var1: []
print "initialize"
do [append var1 now/precise]
func1: [] [print "func1"]
]
probe myobj1
myobj2: make myobj1 []
probe myobj2
The 'Do and 'Print are executed during
myobj1: make object! [...]
but do not survive into the object itself. So that code does not get executed
in
myobj2: make myobj1 []
That wasn't what I was expecting to see -- so thanks for pointing it out.
There's no obvious workaround that I can see.
