Thanks Dominika. I tried your suggestion of both png & making image twice as large. Neither made an improvement.
However, if, in your experience, this is the appearance that can be expected, then I am satisfied. I was just comparing my interface with GS’ interfaces, and mine seemed to be lacking, and I thought perhaps there was a trick I was missing.
Thanks all for your help.
