Another new "feature" just popped up. I just shut down my browser, Opera, and reopened it. Now the circle is missing, but multiple wind flags are still there for my station. Temperatures seem to be in a smaller font as well. Will the "improvements" ever stop?
Update - Apparently it is related to a setting I changed in Opera. I disabled "use hardware acceleration" trying to fix a different problem with another web page. That, apparently, has removed some of the graphics from WU which is a little weird. It works fin in MS Sludge though.
