Android Emulator and adb problems

I'm having a problem in that whenever I start a emulator, either manually through the command line, or when debugging from Eclipse, it is never recognized by adb, i.e. '开发者_StackOverflow社区adb devices' will not list it. I have to manually kill and restart adb every time I want to recognize a new emulator. Surely, something is wrong here?

(I'm on Vista 64-bit)

I've had similar problems prior to SDK Tools, Revision 5. The problems are gone ever since I updated to Revision 5 and then 6.

There is one line in the SDK Tools, Revision 5 release notes that might be related

• "Fixes issue with 64-bit JVM on Windows."
