Hi, thanks for reviving this addon. I'm not sure when it started, but Opie ring icons no longer use the TipTac tooltip. Its tooltips appear with the default Blizzard skin and in the HUD Tooltip position (Edit Mode). TipTac handles all other tooltips as expected.

Added styling of tooltip from addon OPie. Will be included in the next release.
