That may not be the best explanation: In the past I could single click on any pinned program next to the (quasi) start button, and then, if I required a secondary or tertiary instance, simply right clicking that icon and selecting the item's name from the resulting splash box would open the desired instance. Most notably, I used this for checking the spelling of a word with two instances of Mozilla, or using two instances of Word for specific things, but this no longer seems to work for me. Now, to open additional instances it is necessary to right click the "peek" desktop option (far right side of taskbar), open the desktop, left click the item desired, right click the "Open" option and then do it all again should other instances be desired at the same time. The only thing more cumbersome than the actual operation has been this explanation. Sorry, but English is increasingly escaping me, so I hope this is intelligible.
