Non-responsive when manually testing

[kdickerson]

Hi! Great job on the Simulator. I am not sure if it's an issue with my device but the whole app freezes when I try to use the manual tester. It goes into a non-responding state. I tried 2 different browsers and used a new incognito window to make sure it has nothing to do with the cache. It would be really nice if you could direct me to a solution. Thanks!

@AlexHelmutSonntag, I don't see any issues with the application. For me, it's performing as expected in Firefox and Chromium.

Can you provide the export string for the machine you're testing? Use the "Save" button (the arrow going into the box) and select "Plaintext" and copy/paste it here.

Thanks for replying. I tried on Firefox and Chrome.

It worked again then after some time went stuck again. I am still unaware of the root cause of the problem. What could be the issue ?
