I don't know why, often after a restart of InDesign and sometimes while I'm using it the Effects Pallet disappears and no matter how many times I use the Windows> Effects menu item and it's shortcut Cmd + Shift + F10 I will not appear. It also isn't in the sidebars. I end up having to go through a bunch of preset workspaces until it turns up and then rebuild the workspace.

Big waste of my time.
