Hello,
Jarek Sacha kindly provided 2 fixes to the Classify Particles. There was a bug 
that prevented to save the autogenerated macro when using spaces in the image 
name. Now it also reports the path of the macro if writing of the macro 
fails.
I updated the 16 bit Euclidean Distance Transform macro so it can run when 
more than one image are open.
The zip file is here:
