I am using Eclipse Juno on Mac OS 10.7.4 and Android ADT.
Some times when copying and pasting code the copy and paste event take place at the previous file that I had opened on the Editor.
It does get fixed restarting Eclipse but it’s quite annoying.
Is there a fix out there for this problem?
I got tired of this bug too.
After a search, I’ve found that it’s a problem with ADT 20 on Juno:

And got fixed on 20.0.2.
Run a check for updates in Eclipse and update ADT to latest version (currently 20.0.3) and the problem is gone =)
