Eclipse android emulator doesn't close when 'x' is pressed

I just reinstalled the new version of Ubuntu, and afterwards eclipse + android sdk and AVD. Now, when I create a new emulator, after it loads, if I press the ' x ' button, both the emulator and eclipse freeze. Even if I close the emulator in task manag开发者_运维知识库er, eclipse still tells me that I haven't closed that emulator. I fix the problem by restarting the pc, but that can become frustrating after a while. Has anyone had this problem?

Thanks in advance.

Yet not meet this problem. What's the version of your eclipse? You'd better use RCP eclipse for android development. The URL for RCP eclipse: eclipse-rcp-and-rap-developers
