She is restarting computer probably.

It happens sometimes with my MetaTrader. My demo and live account with Alpari and when the market is moving very fast (it was on Friday for example) I can not open or close the order: I am waiting for the new price and finally I got the message: "No connection" and then I am doing it once again and so on. Seems there is some software which the brokers are using and this software is adjusted to some spread and when the market is moving very fast ...

It was on demo only and never happened with live account.
