I have made another observation which may (or not) assist in the debugging of the feature.
When a node points to a system folder eg. %MyDocuments% then it would be expected for that node to open the system folder for the currently active LBC Dock.
As part of my testing I have both the Colin  and TFC docks active side by side (in either account - makes no difference) but whichever Dock's virtual "MyDocuments" node is accessed, it always produces the %MyDocuments% folder for the current active user account as opposed to the desired target for the "targeted" user's LBC Dock.
I was actually trying to ascertain whether I could simply have both docks active in the system quickstart tray and then select whichever one I wanted to use according to which account I was logged into.
It makes no difference whether both docks are active side by side or if one of them is minimised.
Don't know if this info helps but somebody once said "information is power". It may save you the effort of testing that aspect for yourself.
Almost forgot 1.138.03 now being utilised.

 I can confirm my case is fixed. :Thmbsup:

Now that you're simply creating a new appropriate node I can't imagine you need me to test for any further combinations that might cause exceptions. And of course, if a newbie  :-[ does it wrong I can just delete the surplus node without fear of tragic consequences :)

ps1 Phew, that was lucky, can you imagine the fix effort if it was corrupting the data as well.

Still the Same. Here are the "snaps"
