R devel - Aug 2001 - (PR#1065) X11 protocol errors after all x11 devices are

I've fixed the original report and Tom's first.   Someone had
incorrrectly
arranged for most of the initialization to be done only once per session.
I did ask before 1.3.0 what the intention was ....  For pseudocolor devices
at least this was biting since the palette was not re-initialized.

I don't see point two on my system, and Martin's point about
interruption
was first shown to me by Guido a year ago, so is unrelated.

I am going to close this topic: Tom and Martin feel free to re-submit
your reports separately.
