Noted in the last digest that you were contemplating installing a
Pop-Up stopper. The one you mentioned was Pow! from AnalogX. While I am a
big fan of his work and use several of his tools, I would like to recommend
in the particular case that you check out Panicware's Pop-Up Stopper,
available here. There's a
free version (which is the one I use) which can quickly be switched off/on
by double-clicking the systray icon (which changes its display to indicate
enabled/disabled) and plays an audio alert when pop-ups/unders are stopped
(in case you forget you enabled it and can't figure out why that page won't
open). You can temporarily disable it (for the current click) by holding
down the Ctrl or Shift keys while clicking. Very handy.
