OK so I tried this... doesn't work. The problem is that indeed then only the paragraph containing the math inset is redrawn (as shown by debug output), including the inset -- but somehow the corner markers are not reset. I get the impression that without the updateFlags statement, the whole inset is hierarchically refreshed*), but with that statement, _even including SinglePar_, no real refresh appears to take place. *) Even so, that moving the cursor somewhere in an math array inset will refresh corner marker "turds" left in other cells of this inset, and at various nesting depths -- I had for testing modified only "cursor right", which then started dropping these turds. This is mysterious. - Martin
