Hi all, I saw that there are a few issues about images saved on an operating system not working when opened on other operating systems: - https://pharo.fogbugz.com/f/cases/19852/Unable-to-open-image-in-OSX-after-it... - https://pharo.fogbugz.com/f/cases/19869/Infinite-loop-on-mac-when-opening-an... - https://pharo.fogbugz.com/f/cases/19272/Image-freezes-on-Linux-if-it-was-pre... - http://forum.world.st/Image-freezes-on-Linux-if-it-was-previously-saved-on-W... I gave the fix in case 19869 a try and with it I can save an image on windows and open it on mac, however, there are some side effects. First several folders having the following name are created in the image folder: '\Users\andrei\test-image' '\Users\andrei\test-image\pharo-local\' '\Users\andrei\test-image\pharo-local\ombu-sessions' Second, I can only open the image on man once. The second time I get the following stack: [31mPrimitiveFailed: primitive #createDirectory: in WindowsStore failed [0mWindowsStore(Object)>>primitiveFailed: WindowsStore(Object)>>primitiveFailed WindowsStore(DiskStore)>>createDirectory: WindowsStore(FileSystemStore)>>ensureCreateDirectory: WindowsStore(FileSystemStore)>>ensureCreateDirectory: WindowsStore(FileSystemStore)>>ensureCreateDirectory: WindowsStore(FileSystemStore)>>ensureCreateDirectory: WindowsStore(FileSystemStore)>>ensureCreateDirectory: WindowsStore(FileSystemStore)>>ensureCreateDirectory: FileSystem>>ensureCreateDirectory: FileReference>>ensureCreateDirectory OmSessionStore>>resetWithStoreNamed: OmSessionStore>>resetWithNextStoreName OmSessionStore>>store WeakMessageSend>>value WeakMessageSend>>cull: WeakMessageSend>>cull:cull: [ action cull: arg1 cull: announcer ] in LegacyWeakSubscription(WeakAnnouncementSubscription)>>deliver: in Block: [ action cull: arg1 cull: announcer ] BlockClosure>>on:do: BlockClosure>>on:fork: LegacyWeakSubscription(WeakAnnouncementSubscription)>>deliver: [ tmp4 deliver: arg1 ] in SubscriptionRegistry>>deliver:to:startingAt: in Block: [ tmp4 deliver: arg1 ] BlockClosure>>ifCurtailed: SubscriptionRegistry>>deliver:to:startingAt: SubscriptionRegistry>>deliver:to: SubscriptionRegistry>>deliver: SystemAnnouncer(Announcer)>>announce: SystemAnnouncer>>announce: SystemAnnouncer>>snapshotDone: SessionManager>>snapshot:andQuit: [0m So it seems that OmSessionStore is not reset and holds a reference to a the windows path which it tries to create.
