Upgraded to 4.0. Am running coherence, hiding the taskbar. I have the Start Button on the dock. Problem is I can click many times on the Start Button and not get the menu. I will eventually get the menu, but I want it every time I click on it.
I have found that if I click on the dock icon, on or above the word "Start" I get no menu, but if I click in the icon below the word "Start", the menu works.
