Browsing is never easy. For a start, the best chances to browse someone is if they have chat enabled. If you enable the chat icon in the search and download windows, you will see some of a smiley icon, some don't. Those that do will be much easier to browse. This is strictly true for people uploading from you. Oh ... and you need to have chat enabled to via your option settings.

Other factors that affect browsing:
* lack of spare upload/download bandwidth or slots from you or other person. * you or the other person are not properly firewall configured. There's probably more reasons but these are the ones I can think of off hand.

To enable chat column, right-click the heading column of the download window & you will see chat option. Same applies for the other windows.
