18. "Warning unresponsive script" : How do I deal with this ?

This message may come up when you have clicked to view a paper you have already annotated.
It happens because the Javascript is probably too memory heavy for your computer. Just click "continue" every time the message pops up, and eventually the paper will display fully.

Please DON'T click "Save" before the script has finished loading (or afer cancelling the script) as this will only partially save your annotations.

Another remedy to stop this problem from occurring is to allocate less RAM to SAPIENT when starting the server.
For example you could try "java -Xmx249m -jar sapient.jar Server".

Finally, the more expensive solution (with long term benefits, though) is a RAM upgrade.
