Google Chrome I use.Which browser are you using? I can't seem to replicate that.
Default style this way
Can you post a screenshot of that same list on the default style for me?
If you'll submit a ticket with an admin login I can take a look. I can't reproduce this on my styles at all.
I've sent his login information.We don't modify the menu's at all, so the overflow: auto is there by default, I haven't had this reported by anyone else, unfortunately.
