So a perfect candidate for a string extension package. A real modular entity that could load each of them individually would be perfect but we donât have the proper tools, yet. Unless of course every of those algorithms is composed of multiple classes and would fit naturally in a package. But the most important prerequisite would be to make a separate package out of it. Did I understand that right that those are part of biosmalltalk? Then the problem is that useful things are buried in a specialized application. I encounter this often that I donât know about some code because it is buried inside another project. Or I know about it and cannot use it because it is tied closely to a project. my 2 cents, Norbert > >> You have a lot of options for research.

I did a fresh 3.0 install when I got the latest walkback ... I had not even dropped in the files from latest.zip yet. I have insomnia, so please bear with me ... I should be asleep at this hour ... debug log attached BTW - Why are we not naming these log files for the image that was running when the log was written ? r On 26 February 2014 04:36, Sven Van Caekenberghe <sven(a)stfx.eu> wrote: > > On 26 Feb 2014, at 01:57, Robert Shiplett <grshiplett(a)gmail.com> wrote: > > > I am running from that latest.zip tonight and PackageTreeNautilusUI > >>update is getting a walkback messageNoUnderstood for > > receiver of >>protocolsFor: is nil > > > > I simply flipped to class view in Announcements and then flipped that > toggle back. > > > > Does this need to be reported, or is Nautilus still known to be unstable > ? > > I can't reproduce this either, please be more specific. > > BTW, Nautilus is stable and used daily by the whole community.

this was a new image and all I was doing was bringing up the System Browser I have run Pharo on this old XP SP 3.1 laptop on my writing desk for a few years now ... it was disappointing to encounter, as I am expecting Pharo3 next month and then in April, the next WIndows 8, so I sort of had in mind that this sort of thing was not there ... no method had been changed, nothing had been executed with CTRL-D in a workspace ... strictly the most basic sort of sanity check, and that only because I am not used to just copying down latest.zip I will look to reproduce now.

I can't reproduce this either, please be more specific. BTW, Nautilus is stable and used daily by the whole community. Of course, it is a complex piece of code with lots of UI and system interactions, so issues are always possible. Sven
