Links Message Box
The link message box is used to signal dependency
problems when removing items from a tree (like functions and
matrices).
Taking as example the matrices, there are possibly several items in the projects that are dependent
by a matrix (functions that have it as input, presentations or charts
that show it), therefore to remove a matrix you first need to remove
all the dependent items from the project.
This error shows which items are dependent by the one you are trying to
remove.
Clicking on one of the links selects and shows the item in its tree.
Clicking the Ok button this
dialog is closed.
