I recently upgraded to 1p4 from 1p3. I uninstalled the older plugin and installed the new one. The new one appears to work fine. However, I get a dialog each session saying: "an old 1password extension is still installed in safari. it is important to uninstall the old version and use the new 1password4 extension instead." when i check, i only see the new one present.
this is a bit annoying to go hunting. any ideas?
