I have been using a Fiji macro where getDirectory is used to identify the location of a group of files to be processed.
The macro has been in use since May 2014, last update 28 Sep 2015. Now (last few weeks), when the macro gets to the getDirectory statement it just hangs. (It used to do this occasionally, but restarting Fiji fixed it)
The lines of code where this first occurs are:

//Opens file browser and prompts for the location of the images for the Signal/Noise test
  print("Choose the directory where the ||Signal/Noise|| images are stored:");
  print("(Usually [date(yyyy-mm-dd)]\\PAT1\\STD1\\SER2)");
  SigNoiseDir = getDirectory("Choose the Directory") + File.separator;
  print("  ",SigNoiseDir);
  print("");

I can supply the earlier part of the macro if it would help but I do not think that it will be useful. getDirectory works fine with the pre-set directories, but is not offering the choice of directory and I cannot use the preset directories for the data.

It used to work brilliantly, but no more. Is it a version problem with Java? As far as I am aware, I have followed the syntax OK. I would be grateful for a solution. Thank you, Martin.
