Subject: (PR#1065)[Rd] X11 protocol errors after all x11 devices are
Message-ID: <200108231427.QAA19349@pubhealth.ku.dk>

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.

Brian
