sungny,
I would point out that the version of MyEclipse you are running is only supported on Eclipse 3.0 GA Final, you are running a build ~ 2 weeks earlier than that. Can you upgrade to that version of Eclipse and let us know how that goes? Also I’d like to know the Build ID of the MyEclipse build you are using from the Window > Prefs > MyEclipse page (not the Help > About) page. THere are 3 quick fixes you can apply and I wanted to make sure you had them applied as well.
