There was a javascript leak in the UI code for the board. The pages are memory intensive. An easy workaround is to terminate your browser(s) then start a new browser. If you still have the high-CPU-usage problem then maybe something is wrong on your computer. If the high-CPU-usage problem goes away when you start a clean browser, then it's the javascript issue and now you have a way to fix it if it happens again.
