Hello everybody.

Can someone help me with this one?

I'm trying to use comment "(* *)" normally but all I get is some strange
behavior. More precisely, I get "Null" for (nearly) every comment I
use. Ex:

In: 	{1,2 (*Two*),3}
Out: 	{1,2 Null,3}

Or sometimes just errors:

In:	If[2>1, 1 (* then*), (* else*) 2] Out:	

Syntax::"sntxf": "If[" cannot be followed by "(2 > 1), 1 (* then*) ,(*
else *) 2]"

Strangely, when I run the example in the online manual :

If[ a>b ,(*then*) p,(*else) q]

directly from the help notebook everything works fine, but if I copy it
to my notebook, bang, the Nulls are back!

I've noticed also that the text interface does not have this problem.

Any Idea what exactly is going on?

Thank you for your attention
