I am trying to unistall Zimbra Desktop from my Mac OSX Lion and after I send to the trash I cannot remove it because of the following message:

A operação não pode ser concluída porque o item “ant-1.7.0-ziputil-patched.jar” está sendo usado.

the operation cannot be concluded because the item "ant-1.7.0-ziputil-patched-jar"is being used.

This does not permit me to fully clean my Trash, because apparently something is kept opened. Someone can help me?
