Been working on Wordpress for first time for about 2 months...
Found fix in the forum to get the hover behaviour for widgets by adding:
.widget ul li a:hover {text-decoration: underline !important;}
to the CSS inserts section. Works for Pages and Recent Posts widgets but not for the Text widget where I have some links. NB I get the correct colour behaviour in the Text widget using the standard options.
Any ideas on what I can do - I want consistency for links across the site...
