Installed wallet version 1.4.8 on Windows 10. Launched it.
It said "no blockchain". It never downloaded the blockchain.
Node status was a message printed in red color, I forgot what it said, but probably also related to the missing blockchain.
Trying to close the app, it froze - see #2
When running the app for the second time around, it finally started to download the blockchain. Seems fine now, still downloading. Node status: discovering servers.
