StartupPath does not work

Hello,

I hope I have correctly configured ckFinder but I can't make something work.

I want to call in php ckFinder with a custom and dynamic directory path. I would rather not use the baseUrl variable in config.php with SESSIONS.

I think the StartupPath variable would be the good way to set a different directory path each time I call ckFinder, but I can't make it work. Here is my code :

  $finder = new CKFinder() ;                                                                                                                                                                                        
  $finder->BasePath = '/libs/ckfinder/' ;                                                                                                                                                                           
  $finder->SelectFunction = 'ShowFileInfo' ;                                                                                                                                                                        
  $finder->StartupPath = 'Files:/content/42/uploads/content/1/' ;                                                                                                                                                   
  $finder->Width = 800 ;                                                                                                                                                                                            
  $finder->Create() ;

I know the path "/content/42/uploads/content/1/" is correct because ckFinder work if I put this path into "baseUrl" in config.php  

With this code, ckFinder appears correctly but when I try to access one of the folders (Files, Images, ...) I have this message "Folder not found. Please refresh and try again.".

I guess ckFinder does not use StartupPath variable and only use the baseUrl variable (set by default with "/").

I hope I am clear enough =). Thank you very much ! ckFinder and ckEditor are great solutions !
