Lion iCal calendar event shows up as grey rather than colour of calendar it belongs to I have an item in iCal that shows in grey rather than the (blue) colour of the calendar it belongs to.

It also has an interrupted border rather than a flawless border.

What does that mean?

Update: It shows up in the correct colour (blue) on the Web interface.
If someone has sent you an invite and you have responded "Maybe", the Event will show up as described.
