Meta trader going back to full screen after power down

Hi Guys
Although I have been trading for couple of years my metatrader as started playing up
My standard setup is activating Terminal under View
I also activate all tool bar settings
I then go to template and save the chart with the various indicators settings
When I close down metatrader and then open the platform the various currency pairs are displayed correctly
But the terminal settings and the view finder setting have not been saved so I have to reinstall these setting again
I have logged out of my live account and installed all the settings again but it will not save the settings
Am I doing anything wrong or should I try reload metatrader from scratch
