iCal event dialog does not go away on Tiger


Couldn't find this in my searches.

I'm running 10.4.1. When iCal pops up the event dialog, it has the three buttons on the right side. I try clicking the one to acknowledge the event and make the dialog box go away but the box does not go away. I click and click. Eventually it just sorta decides to go away.

Anyone else having this problem or am I special?
