Hi Dal,

Sorry I can't reproduce this. Try this macro:

  run("Blobs (25K)");
  makeLine(21, 91, 222, 146);
  run("Set Scale...");

The dialog proposes a distance of 208.38 pixels, which is the length of the line.
I'm using ImageJ 1.50e26 (the current daily build); Java 1.6.0_65 [64-bit]; Mac OS X 10.6.8.

Michael
