yeah i've seen it in several stocks on my comsec Iress, i believe it's actually a technical glitch, one day it was happening in AGS for over an hour...exactly as you described it. It's qite annoying, and i checked it against the normal cmsec which u need to refresh and is not dynamic, and it was also happening there on the same stock. So i'm sure it was a fault with the comsec system, is yours comsec, or other ?
