IsMovePossible after changing RootedAt for a TJamShellTree
Question / Problem
It appears the TJamShellTree.IsMovePossible() function no longer works after changing the RootedAt property.
Answer / Solution
The history is cleared if you root a JamShellTree at a different folder. The reason is that you usually have an entire different branch of the shell namespace available in the tree control and can't simply move back to the old folders as they are most likely no longer part if the display branch.
