PHP Code Widget inserting an extra <li>?

I first thought this was a WP Widget Cache issue, but reading the comments on PHP Code Widget, now I’m wondering if that’s causing my issue.

It doesn’t happen every time, but every so often an extra li is inserted in my code.

So I see `<!–WP Widget Cache 0.25.2 (http://www.mashget.com) Begin –>

• <div class=”execphpwidget”>`

  Could PHP Code Widget be creating that somehow?

  When it happens, my CSS applies a style to the whole section thinking it’s all one big list item.

  Any suggestions on what to look for would be appreciated.
