Hi Nigel,
I need to know what version you installed and what patches or updates you applied.
When re-installing, it is best to completely remove all traces of the old installation. This includes cleaning the registry:
Before you uninstall, run Unregister.exe from your SS installation folder.
You can find it easiest by right-clicking the icon that starts SS and clicking Properties. Then click the Open File Location button.
Double-click on Unregister.exe; it will run silently and quickly.
After you uninstall SS, delete the ShipSim2008 folder under VSTEP.
Install SS and any updates by following the flowchart that you can find here:

If you still have no secondary control column, please post a screenshot of the controls menu.
Regards,
Marty
