There are other windows you may want to jump to.
The Main window allows you to view Activity, to change the number of bars read, and such. If you load a minute file that is too large, it will take too much time to calculate the pivots, and this will interfere with viewing updates. Choose a smaller number of Bars Back. If bars back is too small, you may not be able to view the minute file as, say 60 minute files.
The Contracts Window shows you the list of stocks. Double click on a stock and it will get updated from IB, and show the real time chart.
The accounting window will show you your trading activity.
When the IB window comes up, you can see the Contracts window behind it:
If you prefer to see the Accounts window visible when IB first comes up, uncheck Contracts visible.
