can any one tell me how to get the tool bars in columbs around the drawing site again
That might not be your problem but, at the bottom of your screen, there should be an icon that looks like a cog wheel with a drop down arrow next to it which will list the different workspaces available try each one.
The named workspaces are listed above the separation line, so if there is only one this isn't the cause of your problem. If the cog symbol isn't there click the 3 horizontal bars at right and select 'workspace switching' from the list.
