I first noticed this with my own web pages, but it is happening now with http://goprism.com:8000/controlpage?name=1st_floor. While viewing this page with Safari, the bottom part of the browser window flashes every second with the text, 'Loading "http://goprism.com:8000/controlpage?name=1st_floor" <n> of <n> items', where n increments once per second. For the page above n starts at about 44 and increments forever. While I have been composing this message it has gone to 174. I have not verified this with other web browsers; I think I will right now....
Nope Firefox does not do it.
