Hi.
I am sorry for that.
This is valuable feedback for me.
Please check whether on the settings-page the option ?simulate spam messages“ is unchecked.
If this option is unchecked and the problem still exists, please press f12, go to ?console“, press f5 to reload your page: If there occurs any exception or a warning please post it.
If you like, we can make a Skype-call to fix this.
Cheers
Matthias
