There's Continue on error option:

I have this problem too. It stops whenever there is access problem and it doesnt retry automaticly because it gives you information if I would like to see the error...This doesn't make sense and I should be able to disable it...

What kind of errors/warnings do you mean?

Hi,

If an error occurs at copying a file to a remote server,
it would be nice to have a checkbox on every errormessage or warningmessage like "Do not show this Errror/Warning again"

greets,
