The first time I tried it on Windows, the initial download took a few minutes to start, even though it got many connections quickly. I tried again twice, and didn’t have the same problem again. I don’t know whether it’s related to your latest update or not.
Most of the fixes are on the sender’s side, so if you were downloading from a 0.1.5 node, some problems are still there. It’ll get better as the network upgrades to 0.2.
How long did the initial download take?
