Hi Partick: I also have the same problem -- I called Wolfram since I have Premier Service and got the following answer.

Wolfram has changed the way in which Mathematica 4.0 parses input cells from the way in which Version 3.0 parses syntax in input cells. They told me to put in a space and then backspace to remove the space. This, supposedly, forces the front end to re-parse the contents of the cell into whatever form that Ver 4.0 uses. This DOES work -- however, I FIND that even if you do this AND SAVE the file as a 4.0 Mathematica file, you still have to do it AGAIN the next time you open the notebook. This is a real pain and counterproductive. FURTHEER I have found that, with opening a 3.0 noebook with Ver 4.0, any cell that has multiple lines in it separated by blank lines ALSO does not get parsed correctly by 4.0, yet they ran beautifully in 4.0. My guess is that if you RETYPEED everything anew from scratch in a newly opened 4.0 notebook evertything will be OK. I am really surprised that these kind of parsing errors created by erronously converting 3.0 notebooks got undetected by Wolfram's Beta testing. I expect a correction version to come out soon. I am almost ready to de-install 4.0 and reinstall the older 4.0 version. Since Wolfram people monitor this newsgroup perhaps they can provide us with what their plans are to correct this situation. ....Terry Harter > > Please, help me, it is a real Nightmare ! > > Patrick Musso
