Many thanks for your reply. Under Win 7 it loaded automatically when I started my PC. I realised it was not doing this after upgrading to Win 10. So I uninstalled tbbMeter and reinstalled it under Win 10. Initially, it would not display any data but after consulting the forum I found the solution.
To open/run tbbMeter I click on its Desktop icon. As Win 10 does not recognise the program I have to OK it through the UCA box, as my setting is too high. After I have loaded tbbMeter I have to click on its symbol in the Task Bar for it to appear on the screen.
My Win 10 upgrade was using the MS online system, so was not a clean install. The only program that had a problem was Wordperfect 11, yes I am that old! It is now running with no problems and does not even need the UCA prompt.
