I was on a laptop with a crazy/poor touchpad, and I noticed the scroll bar not working with the cursor on drop-down menus. I ascribed it to the computer, but then I got the same problem on my desktop/mouse. I can maneuver through the drop down with an arrow button but cannot do it by grabbing the scroll bar and rolling the cursor. Anyone else having this issue?
A number of people with Chrome have reported some very strange unrelated issues lately. I am starting to wonder if the last auto-update of Chrome has some bugs. My version of Chrome seems to be working fine so far.
Here are a few things to try:
