error with line of code in diff-doc.js

I'm having some problems with the diff feature and opening word (diff
between word docs). Word opens,
and apperears to do the diff fine but I also get errors ("Object doesn't
support this property or method",
code 800A01B6) at line 47 of diff-doc.js:

46.// Show the comparison result
 47. word.ActiveDocument.Windows(1).Visible = 1;

 I have tried moving line 47 around in the code and it always gives errors.
I have tried removing it and
the diff seems to work the same (but without the error message).

Can anyone help me out on this? Is it ok just to remove that line of code (
:-s ) or ... is there a way of
fixing it? And maybe if anyone knows where the .exe is for word diffs I
might have a look at that.

Thanks in anticipation,

Nicolas
