I have Mathematica 9 Home Edition. My operating system is Windows XP Professional SP3 Recently, I have noticed the following problem: the suggestion bar, that usually appears after each calculation, is no longer displayed, although (I've just verified it) the box "show suggestion bar after last output" on the interface setting page is checked. May the correct working of the software be affected anyway (I don't think so, since the program seems to work correctly)? However, how can I eliminate this problem? Thank you in advance.
