Just came across what appears to be a problem with 4.0.1 release.
Using a textboxResponseArea with multiple lines, previously (3.9.1) when the user pressed return key on soft keyboard they would get a new line and/or the keyboard would disappear. Now the keyboard disappears and the Submit button is automatically “pressed” proceeding to the next page.
Tried to submit an issue for this but issue system doesn’t seem to be available.
