Red error tiles in JOSM
Since I'd upgraded to JOSM 3751 from 3701 I get red Error tiles around my local Imagery tiles. I'm using separate tms-servers for different local map areas but the tiles doesn't overlap. The red Error tiles though are overlapping the tiles from other servers. Is there a way to not show the red tiles?? I'm new to this so maybe I've missed some setting for this.
I also have a problem with cached Imagery tiles. I have a server on my computer for local tiles but when I changed some of them I still get the old images, its not updating from the server. I've tried to Flush tile cache but nothing happens. If I change the menu name for the Imagery then it will use the updated tiles. I've tried to find the cached tiles but no luck...
