Dear Wayne,
Many thanks for sending 1.40d which I have installed - however, when I
go to Analyze>Set scale I still get
Distance in pixels __
Known distance __
Pixel aspect ratio __
Unit of length __
Scale:<no scale>
{} global
Maybe I am missing the point but I am not sure I see how I can use any
of the above to set it to 300 pix/in, especially when I am using 1,2 and
4 (D, K, U) to set the requisite measurements for the scale bar.
m.
PS. BTW, the updater seems not to work properly from my connection at
least. I get a message saying "Image J Updater: Unable to open release

http://rsb.info.nih.giv/ij/notes.html"
