Before creating an Issue, can someone confirm the following behaviour on Windows 10 ? Downloaded and unzipped into the same folder... * http://files.pharo.org/image/70/Pharo-7.0.0-alpha.build.425.sha.eb0a6fb.arch... * http://files.pharo.org/vm/pharo-spur32/win/pharo-win-i386-201711262336-8879e... The directory contains... Pharo7.0-32bit-eb0a6fb.image Pharo7.0-32bit-eb0a6fb.changes Pharo.exe Double-clicking Pharo.exe produces notification... Information Pharo cannot write to the changes file named C:\Users\....\pharo\Pharo7.0-32bit-eb0a6fb.changes. Please check that you have write permission for this file. You won't be able to save this image correctly until you fix this. However if I edit to AST-Tests-Core > NumberParserTest >> testFail to add "My Comment" then close all windows, Save&Quit the Image, restart Pharo by double-clicking on Pharo.exe, and open System Browser on testFail I can see my comment. I'm not clear on exactly how it works but I presume that restarting the Image would require "My Comment" to be read from the changes file, but notepad shows its not in the changes file. So perhaps the error notification is part of a transition in-Image sources and nothing to worry about? cheers -ben
