RSLinx browsing

RSLinx browsing was created by Ferdydurke
Hi all,
we are trying the OPCLabs client demo, we are creating an OPC client application which connects to may servers, including Rockwell's RSLinx (v. 2.52 Gateway licensed). All works fine when we read/write data (local and remote access) ; but we run in trouble when we want to browse it using the EasyDAClient.BrowseNodes method. This works fine for all other OPC servers we tried.
The problem is, we manage to retrieve the first level branches and some leaves, but the deeper ones seem to be unreachable.
According to some forum topics on internet, we should use a workaround to the BROWSE_TO stuff (e.g try/catch the browse-to, then in catch perform a browse-down). Can we achieve this with the OPCLabs client ? This is our last test, if we succees with this we'll buy it.
Thanks (and... please excuse me if my English is not perfect
