Hello Marco,
I’ve just ran your test several times on one of our remote machines using M-RUN and there was no problems typing characters such as the at (‘@’) character.
The only issue was that the object “Private profile” was not found because when I run the test it appears differently then in your GUI Map screenshot.
I’ve noticed there are different reasons why such character may not be typed in certrain machines – Please check in Google solutions to the subject “my browser cannot type the at character”.
Hope this helps.
Thanks,
ZAPTEST Team
