[Windows] Lag when importing encrypted Ed25519 key

Hello! Thanks for this beta, can already tell this feature is going to get a lot of use.. :)

Just a small one so far -- working through everything methodically still.

When I imported my Ed25519 encrypted key from a file on disk and entered the password, there was a noticable lag (around 5-6 seconds) while it was importing. There was no visual cue that the password was accepted and it was attempting the import, so I ended up pressing the button a few times. I tried again and used an invalid password and it took around the same amount of time to tell me the password was incorrect. Maybe just needs to disable the button while it's processing?

Thanks again.
