usually when i type code into a notebook there is automatic indentation. for example if i type the incomplete piece code
the character [ should show as blue to indicate that a closing ] is missing, and 2*x should be preceded by a tab but none of this happens.
Also, using the TMJ palette, clicking a button for a particular style does not have any effect except a beep.
Having said this, if i do close with ] and evaluate the expression, it does return a value, in this case 2. So really it's a layout problem.
i'm not sure what i did but i'd be very thankful if you could tell me how to fix this problem.
note, I am using:
suse linux 10.0
mathematica for students 5.0
