InDesign Effects panel

As JML suggests, it sounds like the Pages and Effect panes are docked together. Bring up either one and look closely for the tab of the other. Separate them, and all should work correctly.

Check if the Effects panel and the pages panel are not docked together. If not, try to reset preferences: quit InDesign and relaunch it while holding down the Shift, Ctrl and Alt keys [Windows], Shift, Ctrl, Alt and Cmd keys [Mac] until you see a warning message asking for confirmation.

p.s. i don't think the adobe website, and forums in particular, are easy to navigate, so don't spend a lot of time searching that forum list. do your best and we'll move the post (like this one has already been moved) if it helps you get responses.
