It is also worth checking if these executions are always synchronous or if that property is breaking down as well.\r\n\r\nIt may be possible to resolve the issue through some queueing mechanism for execution, which should be investigated.\r\n\r\nOn the other hand, we can reduce the number of executions running through this mode by only applying the injected execution mode for global and AMD executions which expect top-level variable assignment to be global assignment."},"comment":{"url":"https://api.github.com/repos/systemjs/systemjs/issues/comments/151758673","html_url":"https://github.com/systemjs/systemjs/issues/814#issuecomment-151758673","issue_url":"https://api.github.com/repos/systemjs/systemjs/issues/814","id":151758673,"user":{"login":"atsu85","id":1206512,"avatar_url":"https://avatars.githubusercontent.com/u/1206512?v=3","gravatar_id":"","url":"https://api.github.com/users/atsu85","html_url":"https://github.com/atsu85","followers_url":"https://api.github.com/users/atsu85/followers","following_url":"https://api.github.com/users/atsu85/following{/other_user}","gists_url":"https://api.github.com/users/atsu85/gists{/gist_id}","starred_url":"https://api.github.com/users/atsu85/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/atsu85/subscriptions","organizations_url":"https://api.github.com/users/atsu85/orgs","repos_url":"https://api.github.com/users/atsu85/repos","events_url":"https://api.github.com/users/atsu85/events{/privacy}","received_events_url":"https://api.github.com/users/atsu85/received_events","type":"User","site_admin":false},"created_at":"2015-10-28T08:09:27Z","updated_at":"2015-10-28T08:09:27Z","body":"Update: my Win7 PC got different version of systemjs because jspm was globally installed (different versions on different PC's) and systemjs version depends directly on jspm version.\r\n\r\n**I found out that SystemJS v0.19.0 works(that comes through jspm 0.16.6), but SystemJS v0.19.1 (that comes with jspm 0.16.7) and SystemJS v0.19.5 don't work.**\r\n\r\n@guybedford if You really didn't manage to reproduce the issue with enabled Firebug, then what was your globally installed jspm version (and systemjs version used in the application) that failed to reproduce this bug?"}}
