Note that although the UpdateManager has downloaded 178 MB (which turned out to be all) of the last resource (all other threads being already finished), the dropdown nevertheless claims to be at only 36% of 183.1 MB. Seconds later it jumped straight to 96%. Seems the figure only includes resources that are fully downloaded. In a case like this that becomes rather misleading.
Note that the download actually seems to be 195.5 MB, not 183.1.
