Ever since updating to 3.7.7 a couple days ago, the sub-menus on my page have a white area long the right edge, about 12px wide or so. I have tried adjusting the width of submenus with no effect. Does anyone have a suggestion about how to fix this?

without a link to your site I could only guess.

My apologies for the omission. It is: http://www.wordpress2.albanystrollroll.org

I just used Firebug and came up with this code which you would put in the CSS Inserts box of the theme options.

.rMenu-ver {
    background: transparent !important;
}

Thank you, lmilesw!

I tried that and it worked. But when I went to the CSS insert block, I noticed the last item already there was this:

ul.rMenu li { margin-right: 15px; }

I also tried removing that rather than adding in the background property, and it now looks even better. The margin was causing the contents to wrap prematurely. But I am curious why a margin would be needed here. Am I breaking something in some other case by removing this?

Thanks again for the prompt assistance!

I didn't look at the code you had there but good find on your part. You aren't "breaking" anything after all it all looks good. Right?
