Usenet Explorer

I have two questions about the posting interface and Usenet Explorer, I read que manual and could not find the answer.

1) What does the "Props" button?

2) What does the "Clone" button?

And regarding downloads, if I select 500 attachments to be downloaded and my computer crashes (we have electricity cuts in my country), and then I restart the computer, will Usenet explorer keep downloading the posts I selected or will I need to reselect again? (Same situation for posting, ie I am posting 2000 binaries and computer crashes at post 1211)

Thank you

Props means opening edit menu->properties->post

Clone means create identical post (a duplicate), the old post is still preserved.

To save tasks edit menu->properties->general->save queue every x minutes, or when you mark for download something big invoke ctrl+s (file menu->save all).

But it is a good idea to have UPS as well with EMI filter, hard drives I think protected from outage, but there also peaks (e.g. because of lightning) which may get through and kill power supply or fry something on motherboard.
