This has been an intermittent problem but today it is very consistent. Unless I am on the home page, I cannot access any other boards through the menu. When I mouse over "chowhound" on the top menu bar, the board menu appears, but as soon as I mouse down to select a board, the menu disappears. I have to back-button to the home page and select boards from there.
I just had a Flash update on my PC at work (haven't looked at CH from home recently)--could that be the problem?
