Opus crashes in FTP with navigation lock on slow connection

When i am using split panes for FTP with Nav lock on and i select a folder in my local panel, if the ftp directory has not fully loaded and i double click another folder in the local directory Opus crashes and needs to be restarted.

I am on a satellite broadband connection so it is quite slow to load the ftp directory.

Ideally when i click on another folder in the local directory it should cancel loading the previous ftp directory and move on to loading the new ftp directory straight away.
Any help appreciated.
