If I click on a link which has a pop-up window (the sort that I want to see) instead of popping up immediately it waits nearly ten seconds 
During this time there is no internet activity (beyond the split second needed to fetch the data), no CPU usage and no HDD activity. There is also nothing in Event Viewer.
I am at a loss, any ideas please?
(I don't use IE as my regular browser but sometimes I need to, and on those occasions this anomaly is slowing me down.)
