I'm having a problem with windows explorer after clicking item on the navigation pane explorer doesn't switch focus to the folder list on the right it's still focusing on the navigation pane. Same thing with picture preview pane (Alt + P). You may not notice this problem if you are using a mouse.I tend to use the keyboard a lot. I tried vista navigation pane and it doesn't have this bug. I'm using Windows 7 RC I'm not sure if microsoft fixed this bug on the RTM. If you have it please reply.
