Opus crashes in FTP with navigation lock on slow connection

Hi,
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.

Thanks
Fergus
