saguaros I don't think you understand what I'm saying. I mentioned Megamenu ONLY to rule out a possible connection.
Please look at my site, the sidebar, and the link in question.
There is no setting for the MainMenu module that tells it to not allow a parent link to be clickable if there is a submenu. Yes, there is a way to turn off the submenus for a menu module, and there is a way to set which "start level" you want that menu module to begin, but nothing that would do what is currently happening. If I am incorrect, please direct me to the setting in a menu module to correct this as I see nothing.
This bug shows up in all browsers. The link of any parent menu (with a submenu) item in the sidebar is not clickable even the the link is there (as seen when you mouse over the parent menu item).
UPDATE
I've isolated the problem.
In the Sidebar, when the parent menu item (with a submenu) has a link image, the parent menu item is no longer clickable even though the menu item's title changes color when you hover over the link image or menu title. If I move my cursor just PAST the menu item text, clicking on the space just to the right of the menu title, the link works.
If I remove the link image from the parent menu that has a submenu, the parent link works perfectly.
So the issue is that somewhere in the code, the clickable area (like a hotspot link) is being moved out of rage because of the link image.
Again, all of the menu items in the sidebar work perfectly even if they have a link image. It is ONLY when a menu item has a submenu ... and the parent has a link image ... does the parent link not work if you try clicking on the link image of menu title text of that parent link.
If you look at the Sidebar of my website (as I mentioned in my original post), you'll see that the link for "The Band" does not work correctly even though it shows as a link to a page when you mouse over the link image or the title, The Band. When you move your mouse cursor just to the right of the letter "d" in The Band, the link works when you click it.
