changing size of thumbnails causes a freeze

[dbini]

Hello. I was in the middle of a workshop today and I wanted to increase the size of my media bin thumbnails to assist in deleting multiples, but Izzy wasn't happy.

Changing the thumbnail res in the Settings menu opens two instances of the dialogue about regenerating, and one of these refuses to go away, so I can't close the Settings menu.

I needed to quit Izzy to get rid of the dialogue.

I'm on Intel Mac with the latest Izzy. Anybody else having this issue?
