The icon on the right hand top of the screen - I think it is the toggle inspector has disappeared for me, it is the one that in live mode it will show watchers, bids etc and on a completed sale you can click into the order. It has just gone. Can anyone explain how I can restore this please? Thanks
Can I add that I can bring the icon up by clicking a double arrow icon at the top right which also show Scheduler and Accounts, but all are greyed out, in any mode.
On the menu bar, right click and choose “Customize toolbar”. All the menu buttons come up. Toggle inspector is on the list. Drag it to your menu bar in the position where you want it to be. Add spaces or flexible spaces to locate it where you want to be.
Thank you RLMartin for your help, I did indeed go into the Customise Toolbar window, the toggle was in the toolbar but was still only viewable if you pressed these two chevron icons (a bit like arrows) at the top, and it was still greyed out. In the toolbar option I took away the wording, and just had the icons, this appears to have solved it, maybe my toolbar was too crowded with both, I definitely do not have all the shortcuts in it. A bit odd but thank you for pointing me into the direction of the customise toolbar as by taking away the wording in there it has somehow solved it! Thank you 
Try a restart of GS and maybe even the computer. The “Microsoft” solution sometimes works on an Apple computer as well. Try adding the words back again. Sometimes a computer will loose part of it’s programming and needs restarted to get a fresh copy. Too many icons “crowding” isn’t likely the issue because I have 19 plus flexible spaces.
Thanks for that, did that, it still reverts back to this chevron and the toggle inspector is greyed out. Very odd. Will leave the words off.
