IMCE doesn't integrate in TinyMCE

I'm using IMCE an TinyMCE. IMCE offers an option to set itself as the default file browser in TinyMCE, but this doesn't work properly.
I noticed that IMCE should load 2 JavaScripts while displaying TinyMCE to put a button to be able to access the file browser by the image function.
I don't know why IMCE doesn't put the JSs in the page, but perhaps it may be of interest for other people having the same problem:

To make it running, it's necessary to put some code in "tinymce.module":

1.)
Search the string if (!$is_running) { . It should be somewhere in function tinymce_process_textarea($element).

2.)
Add the following code:

$is_running = TRUE;
$tinymce_mod_path = drupal_get_path('module', 'tinymce');

//And now the changes to make it going

drupal_add_js('var imceBrowserURL = "'.url('imce/browse') .'";', 'inline');
drupal_add_js(drupal_get_path('module', 'imce') .'/imce_set_tinymce.js');

//That's all ^^  ...

Now, while using TinyMCE, the necessary JavaScripts will also be loaded. This should normally be done by IMCE. So It could also be a bug of IMCE.
