This macro:

Window.alert('ok')

results in error after successful alert display:

Traceback (most recent call last):
  File "<Script Block >", line 2, in <module>
    d
NameError: name 'd' is not defined

The macro file has Windows line endings and ends with a single newline (\r\n).

There is no error if the macro ends with two newlines.
If the macro has three newlines at the end, the error is:

Traceback (most recent call last):
  File "<Script Block >", line 4, in <module>
    c
NameError: name 'c' is not defined

Convert the last macro to Unix line endings. It ends with 3 newlines (\n). Error:

Traceback (most recent call last):
  File "<Script Block >", line 4, in <module>
    d
NameError: name 'd' is not defined

This is a new bug only in version 7.
My actual script, which was ok with version 6, looks like this:

#language="Python"
if 0:
    pass
else:
    Window.alert('ok')

It has windows line endings and ends with 3 newlines

Now this gives error message:
invalid syntax
Line 8

Line 8 is the end of file. Remove the last line and it runs fine. Other variations of the number of trailing line endings and indents give errors similar to the first post. This is quite mysterious.
