When I let my connection sit for a couple minutes, sometimes only 5 or 10 minutes, I am unable to list directories or move files. The system retries many times and sometimes I can fix it by going back to my bookmarks and reconnecting from there. Other times, I can't even do that and in trying to reconnect, the program hangs and I have to quit and start it up again. I checked my server and everything should be fine but can you help me remedy this? I just updated to 4.7 so I will let you know if that fixes it but otherwise, this is an annoying problem; annoying enough that I would use another program if it worked better (I also have problems with Filezilla so right now, Cyberduck is the lesser troubling of the two). Thanks.
