size calculation problem

Might be a bug not sure, but im doing a direct upload to a folder on a ftp ok. I made the new folder, right clicked in there, and selected 3 sizeable files ( over 100 megs ) and set them going.

In the queue screen at the bottom, when I click connections, it cant calculate the total of Mb's going up, so it will read say 54.6/0 bytes and also time left is ??.??.??

Is this an issue with SFTP or is it the remote set up causing this.

Nice SW btw - better than the rest by miles.
