 * Very strange behaviour in the pro version 3.8.4, it was also the case for 3.8.0
 * When I create a uploader and uploaded file instance, when I want to edit now 
   the uploader, the uploaded file becomes a uploader.
 * When I create multiple uploader, I can only edit one, I cannot access the others.
 * Thx for your feedback

 * Is this plugin tested on an Windows IIS installation?
    I’ve another wp installation(
   not windows) and no issues over there.

 * Yes it has been tested on Windows IIS installation, but not exhaustively because
   most users work on Apache web servers. A common problem with Windows web servers
   is strange file and folder permissions, which sometimes cause problems.
 * I do not know however if this is the case for you.
 * What do you mean “when I want to edit now the uploader, the uploaded file becomes
   a uploader”?

 * Indeed the file browser doesn’t work correctly.
 * What I mean: When I try to edit an existing uploader instance and there exist
   already an uploaded file (browser) instance, the uploaded file (browser) instance
   becomes a uploader instance. It isn’t anymore in the browsers instances but it
   is now a uploader instance. Difficult to explain.

 * Ok problem solved, but I had to do a change in a plugin file. In file **wfu_functions.
   php** I modified function **wfu_create_random_string** and replaced line
 *     ```
       mt_srand((double)microtime()*1000000);
       ```
   
 * with line
 *     ```
       mt_srand((double)substr(uniqid("", true), 15));
       ```
   
 * The problem was that the web server is too fast and there was no sufficient entropy
   when microtime() was called consecutively. In simple English, this means that
   generation of random numbers was not working properly and this was affecting 
   the behaviour of the shortcode editor (and probably other plugin’s features).
 * I will examine if the above solution works in all cases and put it in the next
   release.
