BugFix v3.0.3 - For Windows users

[BennyThadikaran]

A bug affecting windows users has been fixed. The bug was accidentally introduced in version 3.

On Windows, threads are executed by importing the main module and executing in a python interpreter.

Prior to v3, there was an check to make sure certain startup code is not executed using if __name__ == '__main__'. This if check was removed in v3, resulting in the entire script getting re-executed in each thread including the input prompt.

This issue has now been fixed and comments added as a reminder not to remove the if check. Thanks to user Prady04 for raising the issue. 👍
