The issue I'm having is that when in Explorer, I can't use the scroll wheel when moving from the folder pane to the file pane without FIRST clicking somewhere in the file pane. Years ago I had a mouse
driver that allows that and haven't seen that functionality for quite a while now. If anyone knows how to get the scroll wheel to work by placing the cursor within the pane (without having to click inside of that pane), please share how it's done. I miss that functionality!
FYI, the functionality I'm looking for in Explorer does work in Thunderbird. Clicking on a folder, I can hover over the emails list pane and begin scrolling that window with the wheel without having to click somewhere within it first.
