I tend several WP sites on various server accounts. I noticed that WF was working, then I accessed it simultaneously from two different WP installs on different servers and now I am having the same issue. I am used to having several tabs open at once, esp. when dealing with low-end shared hosting accounts. :^)
I am using Seamonkey browser. Everything else works that I know of. I do not know how to access JS error console.
I'm wondering if the WF servers have an issue with my accessing different installs from the same IP.
