I highlighted two files on a server, right-clicked and chose download. I browsed to a location on another server to which I often download and started the download. I tried again after this error (it did not remember the destination and I had to browse to it again) and it worked.

Invalid access to memory - TRemoteFile::Duplicate

In a remote directory I used ctrl+a to select all files, I right clicked on the files and selected "Download and delete". After a good 10 minutes of transfer I selected "Minimize" then "Proceed in background". This is when the error occurred. I can't seem to replicate it.
