A little problem.

[AliasAggers]

A problem has come on my Lenovo computer, working on Windows 10.
There used to be a little spot on the bottom RH part of the screen which, when clicked, came up with a list of all
files on the computer which, when a file name was clicked, took me straight to that 'page'. That little spot has now
disappeared, so that I am unable to get to the item I require. Any suggestions?

Aggers, that sounds like a smart addition of recent files as a taskbar toolbar. Either that or an app. I don't know if this was done by Lenovo but I can't find an equivalent. Perhaps not looking hard enough but it is getting late.
