Start More than one Android Emulator at a time

Question

After I updated my ADT/Tools to 20, I am not able to start Two Emulators at a time.

It worked Once. But i don't remember what i did that time.

I tried restart my system several times.

I don't know how to locate whats the problem in emulator.

the emulator is shown in TaskManager Process but not on screen.

Looks like this bug is fixed in the latest version of SDK Tools, Revision 20.0.1.

From the revision history:

Fixed problems with running more than one emulator and running multiple emulators with GPU acceleration.
