Sorry I don't understand what you mean.
So I will try step by step
For example lets take "some_host" as some host name (exactly it was one of my host names).
About half day ago I had to quickly connect with this some host, for example lets take it as "office.some_host.com". So connection estabilished and other things ... but ...
Few hours later I had to connect with "some_host.com" (without subdomain "office") and I could not connect with that host becouse SmartFTP all time want to connect with "office.some_host.com".
This case is related to quickly connect with ftp, port 21 (via Adress, Login, Password) - without use the favorites.
If I then used Favorites, there were no probs, but some host do not need to be added to favorites.
So I could not quickly connect with some_host.com if I earlier connected with office.some_host.com. I checked it also without cache Enabled etc. And nothing. Some time ago I had similar problem, but I forgot about it becouse some time I have not been using SmartFTP, but since there is SFTP, that is other world
I hope now it is clear, if You want to have more details, please ask about anything
