I don't think this is a bug. I mean, what would you expect?
You can assign a value to a variable, but not to an arbitrary expression.
For instance, the following is a valid assignment:
x = a + 1
But the following is not:
x + y = a + 1
I mean, where should "a + 1" in this example be copied to?
As I see it, the case is similar for the ControlSource, which implies a "store" or a "replace", depending on the case.
