I have installed the newest version of WP (3.4.1) and the plugin (1.8). The problem I'm having is with the mouse-over hover-effects. The "bubbles" appear only partially in the upcoming events widget, and not at all in the menu of the calendar view (the drop-down menu for Month and Filter). When hovering over the actual events in the calendar the "bubbles" show up correctly.
I have tried to find the cause of the problem by deactivating all other plugins except AIOC. But that didn't help and the same problem remains.
Does anyone have a solution?
