Code similar to the following gave me trouble today. I thought it would
be fun to share:
Clear[x];
test[] := Module[
{x},
ToExpression["x=3"];
Print[x];
];
test[];
Print[x];
In my version. "x" was infact the variable "Active" which is an option
to ButtonBox and created a ton of problems. Of course I could not
change the name (user driven, and that's why I am running a
ToExpression on it).
The solution was to not declare Active in the Module and to
Clear[Active] in the function.
any other insight?
