问题
It seems to be a similar problem as the one described in Eclipse cut/copy/paste not working. However, the problem does not seem to be related to CodePro AnalytiX plugin.
At some point after process of debugging, copy&paste and delete keys do not work. Also from Edit menu these options are hidden.
After restart of Eclipse everything works fine again.
System : Windows 7 Enterprise, SP1
Eclipse Juno Service Release 2, updated.
A hint given in Eclipse Forum, e.g. remove key bindings in Eclipse, does not seem to be a solution because it just removes these shortcuts.

This is more often than not a memory issue and I had it recently also. I resolved it by doing the following:
- Open the eclipse.ini in the root of your Eclipse installation
- Increase you memory to at least more than you have now, for example
-XX:MaxPermSize=256m -Xms40m -Xmx1024m
This worked for me...
