Not sure why David removed this... Anyhow I see your point.
I think we could introduce an option to allow to choose between syncing the treeview with network/UNC path or not. This way each user can choose the best setting for his needs.
I have added this to the list of things to do.
I do not find the patched file content neither in git nor in sourceforge. Probably this changes were never checked in...
I am using network/UNC paths a lot and I am using treeview a lot. Therefore treeview on UNC paths is one of the main features for me, without this, I cannot use Explorer++. Actually, that the only point, why I cannot use this great tool.
