Aborting downloads and urn:sha1
 

Could somebody tell me why the abort option is very often blanked out when right clicking a download leaving only the abort all option leading to a su-menu where the only available option is 'with same urn:sha1' What the hell is an urn:sha1?

Thanks, Phil.

What version are you running?
If you want to abort a download, I asume you want to stop and remove it completly? In that case you might be better of to purg the corresponding download pane.
urn:sha1 contains a checksum of a file. Every file has a unique checksum. On gnutella the SHA1 algortime is used.
urn stands for universal resource name. Which means that we are looking for something unique.
So actually
urn:sha1:879871231232 means:
Look up a unique resource by its sha1 which is 879871231232

A download which has multiple sources must each have the same urn:sha1, otherwise they would indicate different downloads for different files.
