HTML Summary Pages; Popup Notes; text may overlap the popup boundary

HTML Summary pages can contain popup notes (small yellow icons which when clicked, popup more information).

In the CSS style sheet supplied, the class div.ISPopupNote restricts with width of this popup to 240 pixels. If the note contains text with no spaces that exceeds this length then the text appears to overflow the popup.

The following has been added to the CSS class to prevent this happening:
word-wrap:break-word;

The CSS file (general_1.00.css) has been updated but, since this is a small and obscure change, the version number has been left unchanged.
