I downloaded latest release of EA now and still same issue.
I noticed that its taking 420 MB, as per windows 7 task manager.
But SQL developer 3 takes 170 MB only.
Connections are not happening now, the connection progress bar in lower right corner of screen is still in progress after 15 mins...
I have Win 7 64 bit, Core i5, 4GB RAM, 48GB free space as of now
What can be the issue. ??
