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

and even if it would be unstableâ¦ issues needs to be always reported, is the only way to be aware :) On 26 Feb 2014, at 07:45, Esteban Lorenzano <estebanlm(a)gmail.com> wrote: > Nautilus is not unstable. > That should not be happening and in fact I cannot reproduce it. > Please report. > > 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 ? >> >> thanks >> >> I'll go back to my older 3.0 candidate for now ... >> >> R >> >> >> On 25 February 2014 19:02, Esteban Lorenzano <estebanlm(a)gmail.com> wrote: >> none >> >> just download this one: >> >> http://files.pharo.org/image/30/latest.zip >> >> is always the latest effective build. >> >> Esteban >> >> On 25 Feb 2014, at 21:05, FranÃ§ois Stephany <tulipe.moutarde(a)gmail.com> wrote: >> >> > I'd like to download the latest Pharo 3 on the CI server but I don't know which one I should download? >> > >> > The last one on the list? >> > <Screen Shot 2014-02-25 at 21.03.07.png> >> >> >> >

Nautilus is not unstable. That should not be happening and in fact I cannot reproduce it. Please report.

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 ? thanks I'll go back to my older 3.0 candidate for now ...
