v6.0.1 problems translating previous notebooks...

As I mentioned in 'Another v601 problem ...' above, dated today 9/1/2007, I had a problem translating a v5.2 notebook which worked fine before v6.0.1. The 'problem' turned out not to involve 'Piecewise' at all, but rather that Mathematica v6.0.1 has inserted extra spaces "" into the equation line, which are invisible to the user at first glance. I found them, finally, by noting that, side-by-side, one instance of the variable 'r' was colored blue (unknown) while another was black (???). Rewriting the subexpression did recolor them both blue, but now I got the error 'xxx cannot be followed by ""'. Hmmm. Using shifted left arrow (<-) I was able to highlight the extra spaces and delete them. (Simply putting the cursor there and deleting did not work.) Then everything was fine. Sheesh. I gather one must suspect the simple notebook translation algorithms. This was, by the way, *after* applying all the 'suggestions'; Mathematica 6.0.1 said it could not translate the specific line, which started my troubleshooting. Hope this may help some others, or perhaps this is old news. Dick Chaffer Bozeman, MT
