Don't know if this is just me or if it's a specific Windows 7 issue.
Navigating through Explorer sometimes you need to find out some information about a file. Hover your mouse over the file and you get information. I was looking to see if any of the tracks on an album were larger than expected thus containing a secret track at the end.
Why is it the mouse over works sometimes and not others with no seeming pattern. You hover over some files and you get info, some not and some will eventually if you move away and back and away and back.
