Hi there,
In most of the normal cases delete button in CAS view works fine. But when we perform following sequence of tasks, 'delete' button stops working:
1. Create two function, let the function be f(x) := x + 2, and g(x) := x + 4
2. Create a new function r(x) in terms of f(x) and g(x), say r(x) := f(x) + g(x)
3. Delete f(x) and g(x) [It will work fine]
4. Now try to delete r(x)[Even if you click multiple time on delete button, it can't be deleted]
Workaround in GUI.
1. Replace r(x) with some function defined in terms of x instead of f(x) and g(x), like r(x) := x + 9
2. Now click on delete button[It works!]
Thanks,

The same problem 
Hi,
Function r(x) has defined in terms of f(x) and g(x). So it might be a good idea to clear r(x) when either f(x) or g(x) or both gets deleted.
Currently if we create three functions f(x), g(x) and r(x). f(x) is defined independently, but g(x) is defined using f(x) and r(x) is defined using g(x). In this case if we delete f(x) then other two functions get cleared automatically and everything works fine.
Thanks,
