I am using atahualpa 3.7.11
I created a page menu with 2 levels of sub-menus. You can see it here:

When one clicks on the menu and the drop-down menu appears, when it retracts there are horizontal lines remaining over the body text - in the places where the drop-down menu items used to be. I do not know what is causing this or how to remove them.

Please help!

Looks like a browser bug. It is fne in Safari and Firefox on a mac, but the lines show up in chrome.
Try shutting off the animated menu's at ato->MENU 1 (Page Menu)->Animate Page Menu Bar

Thank you - I will try that. BTW it does seem to show up in Firefox and Safari on the Mac... It doesn't at first but if you're on the pages for any length of time it seems to start popping up.

Let me see what happens when I turn off the animation. Thanks.

I just turned off the animation - looks like that fixed it! THANKS!!!
