Hello,
I’ve been using the wallet for a while. For the first time I am having this issue. I change the computer. It has 8gb of RAM, which should be enough. Any ideas why?
I am importing private keys. After 2-3 commands, sometimes 5-6, it is getting stuck and I can’t fix it until I restart the machine. ctr + c doesnt work 
When you import a private key it has to scan all blocks to find transactions for the new address. Its a lot of data, its a lot of work, takes time… patience.
BTW, you don’t need lots of zaddrs, you can safely re-use them without compromising privacy.
