On the top menu click Layout then Page Setup... In the resulting Options dialogue box click the + sign next to Workspace to expand it. Click the + sign sign next to Customization and then click on Command Bars. In the right pane tick the box next to Toolbox.
Thank you. Under View there was no 'custimize' offer but on the drop down menu from Tools was 'customization' which had several empty boxes including 'toolbox'. When ticked all is now well, Thankyou - Wol
