i7 MBA 10.7.2 DL 1.7 main display switching issues

[bwmartin]

Does anyone know if the clamshell mode problem described in this Apple forum (https://discussions.apple.com/thread...rt=15&tstart=0) was (or was supposed to be) resolved with the recent recent 1.8 Alpha 1 driver release?

I'm having this same problem in 10.7.3 on a 13" MBA. I just downloaded and installed the latest DisplayLink driver (1.8 Alpha 1)—even uninstalled the old one first using the uninstaller included—and had hoped that this would help but I am still having the same problem.

I have one monitor running off the Thunderbolt port (using the Mini DisplayPort to DVI Adapter) and another with a Plugable UGA-165 USB 2.0 to VGA/DVI/HDMI Adapter. I am assuming that the one running off the USB port is the problem but I'm not certain.

The two external monitors work fine, but I don't need or want the internal LCD going while it's supposed to be in clamshell mode. (Though obviously it's not actually in clamshell mode; that glowing white Apple seems to indicate that.)

Is this a DisplayLink issue or an Apple issue? How do I go about reporting it to either (Apple or DisplayLink)?

I've only had the MBA a month so I suppose I can call them (Apple). I filled out the bug form that one of the earlier posts on the Apple forum mentioned, but that seems like sending an email to nowhere--no idea if anyone will read it much less act on it.

Thanks in advance.
