Hi,

While testing the latest Revo Metro release (V5.8.6.340), I attempted to submit feedback via the integrated feedback function. After writing the summary and entering my email address, I clicked “Submit.”

The application displayed the error message **“Please input a valid e-mail address”** and then froze. I had to force-close the program using the Task Manager as it did not respond to any further input.

Note that the email address entered was correct, but the validation seems to trigger this hang.

Screenshot in German:
