Resource Browser doesn't go to resource-path defined in manager config

Hello to all.

i have created a subfolder in "/assets/" called "myfolder". I changed the resource-path and the resource-url in the manager configuration to: "/assets/myfolder/".

i have created the needed (and some other) subfolders in "myfolder/":
- css
- files
- images
- docs
- media
- etc.

if i want to upload or insert images in the page, everything works well! the resource browser goes to the defined path:
"/assets/myfolder/images/"

BUT: if i want to link to a pdf-file (for example), which is stored in the "files"-folder, the resource browser goes all the time to the following path:
"/assets/files/"

but it shoul go to:
"/assets/myfolder/files/"

can anyone help me with this?

using modx v. 0.95

Thanks a lot!
