I had then tried older versions of logisim evolution (since it did work on the original logisim) and discovered that the latest version I could get it to work with was 2.13.10 and it does NOT work with 2.13.14. (Note: I had tried to compile the version in between them but was having compilation issues and did not want to spend too much time doing that). Do you have any idea what changed to make it so that tty table is now requiring the graphical interface to load? Like was this intentional or is this just a mistake?\r\n\r\nThanks, Hopefully, you can take a look at this quickly since we want to use this with a project but are having issues where students cannot test their projects because of this issue. (They need to test on the remote server but they still build it on their local machine)"},"comment":{"url":"https://api.github.com/repos/reds-heig/logisim-evolution/issues/comments/404892155","html_url":"https://github.com/reds-heig/logisim-evolution/issues/166#issuecomment-404892155","issue_url":"https://api.github.com/repos/reds-heig/logisim-evolution/issues/166","id":404892155,"node_id":"MDEyOklzc3VlQ29tbWVudDQwNDg5MjE1NQ==","user":{"login":"maehne","id":1174243,"node_id":"MDQ6VXNlcjExNzQyNDM=","avatar_url":"https://avatars1.githubusercontent.com/u/1174243?v=4","gravatar_id":"","url":"https://api.github.com/users/maehne","html_url":"https://github.com/maehne","followers_url":"https://api.github.com/users/maehne/followers","following_url":"https://api.github.com/users/maehne/following{/other_user}","gists_url":"https://api.github.com/users/maehne/gists{/gist_id}","starred_url":"https://api.github.com/users/maehne/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/maehne/subscriptions","organizations_url":"https://api.github.com/users/maehne/orgs","repos_url":"https://api.github.com/users/maehne/repos","events_url":"https://api.github.com/users/maehne/events{/privacy}","received_events_url":"https://api.github.com/users/maehne/received_events","type":"User","site_admin":false},"created_at":"2018-07-13T16:58:20Z","updated_at":"2018-07-13T16:58:20Z","author_association":"CONTRIBUTOR","body":"Thanks for the clarification! The version span 2.13.10 to 2.13.14 definitely should help to localise the change introduced between 2015-08-28 and 2015-12-07, which causes the problem.\r\n\r\n@BFH-ktt1: Do you have maybe an idea?
