Three meetings

Google calendar - potentially useful. Actually irritating. Or is it just me? I find the display really confusing. I managed to enter the same meeting three times because no matter how many times I refreshed the page it didn't seem to be there. But then I went away and came back and it was there and now I don't know how to stop the calendar telling me that I have three meetings on July 6th at 11am. I suppose there's some comfort in knowing that they are exactly the same meeting and that I will be able to meet this triple-booking. Shades of Groundhog Day though...
