Samsung Captivate :: Make Google Calendar Default When Adding New Events

Anytime I click to add a new event it always defaults to "My Calendar"(phone built in one) as the Calendar it is going to add it too.I have checked my settings and I only have my google calendar checked so it shows all of those events.The "My Calendar" is unchecked too. But it always wants to add it to that one, not google. Any ideas how to change this? Or if not, is there another calendar app you could recommend I use instead of the stock then?This is really annoying that every event I have to change and select Google.I use google calendar for everything, and if I forget once it could cause a lot of problems. Plus, I don't want to think about having to change it manually EVERY EVENT!
