Remote+Terminal+Access+Plugin

When using Remote+Terminal+Access+Plugin of Jenkins, the terminal window flashes very quick and cannot see the content inside, like exec top command, impossible to see what it shows.
The rmax value has been tested on jenkins running on localhost.
Meanwhile above firefox 17.0, paste is not working via the link pointed, but without the paste function, terminal still works, so disable the paste if found the browser doesn't support it.
