FTP User Details - User name already exists

Hi,
 
I have a suggestion.
When adding a new Website and you want to add an FTP User you get into the FTP User Details pane.
When you leave the default username and you just fill in the password and then click next, there always pops up a message:

 
But if you then close this message and click the button "Check Availability" it just appears Available.
 
So it's pretty annoying that you have to check availability everytime. Because even when it is available, you will get this error.
 
Kind Regards,

This was the reported issue in Build13 and already been resolved in upcoming HC version. If you want to apply the Stable beta of new installer then please contact support they will provide you download link.

How long will it be untill the new version will be available? If it's not to long, I will skip the beta and wait for the official release.

FYI: HC v9 has been released.
