White Screen

[Balloonist]

I am trying to load a ROM that used to work in the past, but almost randomly it started to boot up with the white scree.  I have read the solution for this is to change the Override to Flash 1 MB, but it doesn't allow me to click the save button.  

Any ideas?

What game? Did you update your build recently?

Pokemon Blazed Glazed. I've tried with version 0.5 and 0.52 on the Mac.
