Set a Default Calendar for New Appointments in iCal?

Question

I never found a post with a sufficient answer to this question. However, it seems as though I may have stumbled on a resolution myself.
iCal has it's own default calendars: Home and Work. I use MobileMe so the MoblieMe calendar is listed there as well. I also have an iPhone 4. I wanted all calendars to syncronize automatically when I create a new appointment on any of the 3 locations (laptop, cloud, or phone). I found that when create a new event in iCal on my macbook pro, it wouldn't update with mobileme or my phone. This was because when I double click to create a new event, iCal automatically puts the new event into my "Home" calendar, even though it was unchecked and not highlighted. As soon as I double click to create the new event, iCal's default kicks in and the Home calendar in the "On My Mac" section suddenly becomes checked and highlighted all by itself and the new event is automatically placed there, never to be updated with the cloud or on my phone.
I think the problem may be related to something I read under "How Do I Set a Default Calendar for New Appointments in iCal?" There a solution given was that the uppermost calendar was being defaulted to and it was suggested to drag the desired calendar to the uppermost position. None of my calendars would drag anywhere. However, I find that if I uncheck Home and Work in the column on the left under "On My Mac" AND then click the arrow so those two calendars are hidden (very important), and then check and highlight the only showing calendar: MobileMe, that (so far) when I doulbe click to create a new event, a new event is created in the MobileMe calendar, and Home and/or Work under the "On My Mac" section never becomes checked or highlighted. So the new event is created only in the MobileMe calendar listed and updates on my laptop, in the cloud, and on my phone.
So far that has been my experience; but, it has been only minutes since I tried that, so let's see what happens after a couple of weeks or so of normal use and see if the problem is actually resolved.

I have been searching for this information for weeks now -- thank you!
This works for Google Calendar as well as for Mobile Me. I'm going to type a little more information here to see if I can help this answer come up more quickly for other users when they keyword search as I was doing.
This answer helped me reset and change the default calendar for iCal. I can now set my Google Calendar as the default calendar in iCal. When I create a new event in iCal, it syncs to Google Calendar as the default calendar without having to choose another calendar. All my iCal new events now go directly to Google Calendar and sync to my iPhone and iPad. I couldn't move the gmail google calendar to the top position, and just unchecking Home and Work didn't change where new events defaulted. Now my new events automatically go from iCal to google calendar, and I don't lose track of any events. I think you can set any calendar as the default iCal calendar for new events using this approach.
