I just downloaded JOSM not long ago, along with the YahooWMS plugin. I have tried using it, but have noticed that the imagery appears to be pixelated and when I zoom in, the imagery doesn't automatically reload in a higher resolution like I'd expect it to. I tried right clicking on the "Yahoo Sat" layer (in the layers panel on the right) and I clicked change resolution, thinking that would make it load a higher-res image. I clicked that and waited, but nothing happens. I don't see why this has to be lower resolution than the SAME yahoo imagery in Potlatch.
Is there a setting I need to change somewhere, or is this a bug? I'm not using a beta version of JOSM. Please let me know.
PS. What was with the server yesterday afternoon? I went to OSM at 6pm PST (pacific standard time) yesterday and it took way longer to load pages and it took an unreasonable amount of time to upload a small changeset (6 nodes, 3 ways) in Potlatch. Was there a REALLY BIG edit/upload going on and slowing the servers down?
