Re: [Pharo-users] Which one should I download?

Hello, Just did a check on Windows 8.1 with Zeroconf on the latest 3.0 and vm and it all works while doing the "kick the tires" procedure (doing this from my MINGW32/MSYS env). One issue tough is that Avast Antivirus gives a problem the first time I ran the VM as it was "deepscreening" the exe and this led to a VM crashed message. Restarting pharo-ui didn't exhibited the issue. Screenshot attached. HTH Phil (... who paid the Consortium fee... :-p )

Robert, Iâve looked at your log. You are using an old VM. (288) Please retry with a newer one (stable/latest) Stephan

robert Are you sure that you really use the latest version? Because I do not see why opening a window would be platform specific and I could not reproduce this problem. So do you have a real way to reproduce the problem? can you send us the debuglog? And BTW Pharo is our and your system and we work all to make it better so no need to be pushy it does not help.

Which one should I download?

by Torsten Bergmann

Dear Robert, I doubt that it is a general issue as I regulary try on various XP combinations (even today) and therefore guess that it is a local problem on your single machine. As you have other images and older VM's floating around it may be an issue that you start the image with an old outdated VM. Note that when you double click the image to start the Windows OS will use the executable (VM) which is associated with the *.image extension. If you had older VM installations (Squeak or other) this may conflict. Just to make sure can you please exactly follow these steps: 1. download and extract http://files.pharo.org/image/30/latest.zip in a fresh directory 2. download and extract http://files.pharo.org/vm/pharo/win/stable.zip into the same directory 3. go to this directory and drag the Pharo image "Pharo-30782.image" onto the "Pharo.exe" to make sure the system is exactly started with this combination and no other VM or image is involved Then tell us if this works or (if it still fails) what the system reprorts to you initially. You should also check: in World Menu -> "Tools" -> "SystemReporter", there you should check the entry "VM general" which will tell you excactly the VM you are running on. If you select all entries in this "System Reporter" you can send the report here so we know more about your environment. Thx T.

"BTW, Nautilus is stable and used daily by the whole community." This still rankles ... I have been a Smalltalker since long before Squeak and have been using Pharo since Seaside first ran on it - if not earlier than that ... I also received from another on the mail list "and in fact I cannot reproduce it." "And in fact" is such a wicked rhetorical move ... in a game I have lost all interest in playing now that I am retired. It may take me a lot of effort to track these 2 bugs down as far as "Follow these steps to reproduce" .. but then I am not a CONSORTIUM member ( I used to pay big bucks for Smalltalk, back in the day ) so may be I am too far outside the "whole community".... btw.
