I notice that the page for drivers (
http://www.displaylink.com/support/mac_downloads.php) still lists 1.7b3, even though 1.7b4 is now available. Two issues.
1. This means you have to know to go up to the forum as a whole after following the download link. Otherwise, you go right to b3 and never know that b4 is available.
2. Should this worry us? Abandoned/non-updated links are often a sign that a company has lost interest in a product. Please tell us this isn't the case (or that it is, if that's the unfortunate case)!
