Browsing "users\public" windows 7 resets

When I try to browse for media on “users\public” on a windows 7 machine it resets to home menu after showing loading content for some time. It works fine when I share a video folder inside the public folder and access that. 

Does the Public folder have any photos inside it? We’ve resolved an issue like this that was caused by loading a folder with 50 or more images.

The folder doesn’t contain the pictures directly, but the subfolder “Public Pictures” contains many subfolders with pictures.
