Hi André,
Sorry for not testing in another browser... I now tried the following browsers, running on Windows 8.1 Pro:
- Mozilla Firefox, version 45.0.1, and it's not working there.
- Google Chrome, version 51.0.2704.106 m, it works there.
- Internet Explorer 11, version 11.0.9600.18378, it works there.
I even tried it on my iPhone5S using Safari, and it works there as well. So only Firefox gives me a problem.
My personal outsystemscloud environment is .NET of course. The environment from the customer I work for at the moment, where we would like to use the FeedbackMessage++ component as well, is also a .NET stack.
