It is now much improved, and the work-around of delete-undo seems to release it every time.
But the elusive little bug is still there appearing very occasionally! The screen shot shows how I finished when I caught it this time. All the moves were logical, filling all cells except those with notes, up to the point where I had to make a choice. Tracker 1 was first tried with the 4 and 9 interchanged, resulting in an unfillable cell, so eliminated. This resulted in the 9 and 4, then tracker2. This is the first try at tracker 2 starting with the 6 on the same row as the blue 9. At one stage somewhere in the whole process, I miss-clicked a duplicated value into a cell when I was trying to click to open a note - getting the red font numbers. I used the click-on clear icon to remove it. On a couple of occasions I mis-clicked trying to make a note, and got the 9 digit icons. I cleared these by clicking 'elsewhere'. Sometimes elsewhere didn't work (not on the grid or not an editable cell) and I had to click a different elsewhere. Thanks for the great improvements since last month. Hoping this helps you find the elusive and hopefully last little bug**r!
