ShowMessage() is not thread-safe.  Do not use it outside of the main thread.

Use ExitThread() instead.  Or just exit from the function normally.  The OS 
will call ExitThread() for you.

You are calling CreateThread() wrong.  It should look more like this:

    ThreadA = CreateThread(NULL, 0, &Thread1, NULL, CREATE_SUSPENDED, &Id);

> ResumeThread(Thread);

If you are going to call ResumeThread() right away, then there is no point 
in specifying the CREATE_SUSPENDED flag.

Please show the actual implementation.

You haven't shown enough code to diagnose that.

At which point in your code?  What does it look like?
