Horsepucky.

That's just a confirmation of Gustav's statement  that the problem is the programmer, not the 
global.

As a general rule, Global's should be set in only one place, but can read/used anywhere.

They should not be used to carry values which can be modified indiscriminately.  (unless you 
are using them in a mulit-threaded application where they are also useful for passing values 
between threads)
