Distance in pixels not automatically populated for line drawn

[dal]

When I try to set the scale for analysis in ImageJ, after having drawn a line of a known length, the pop-up input box for setting the scale does not have the Distance in Pixels automatically populated by ImageJ, so I cannot set a pixels to known measurement scale.  Is there any way to fix this issue?  Thanks for your help.

Analyze>Set Scale works here in the latest build under linux w/Java 1.6

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.
