Yes, I'm having the exact same problems. Quite frankly, this device is not performing as I expected. I initially contacted Greg in Tech Support, but he really didn't offer much help, basically stating the reason for most of these problems has to do with Apple not allowing them to access certain areas of the OS. After days of frustration, I finally emailed Matrox the following and asked them to forward my concerns to their product engineers.

For the most part, my Matrox DualHead2Go Digital ME is performing great. There are only a few issues I'm having that I can really use your help. I currently have the DualHead2Go setup as 2x1 for display 1, which I'm assuming are my two LG monitors, and 1x1 for display 2, which I think is my MacBook Pro 9,1. In terms of OS, I'm running Mac OS X Mountain Lion, version 10.8.2.
So here is where I'm having problems.
- Although MOST applications respect the Matrox Desktop, and will stay within one of the two monitors (unless resized), I've found that nearly ALL of the Adobe Creative Suite applications (InDesign, Illustrator, Photoshop) do not. For whatever reason, the only exception seems to be Adobe Acrobat. From a productivity standpoint, this is a real problem because it defeats the purpose of being able to use multi Adobe apps at the same time on different displays. BTW, I'm currently using Adobe CS 5.
- As you know, with the dual monitor setup nearly ALL Apple and many third party dialog boxes show up in the middle of both monitors, between the monitor bezels. This makes viewing the dialog boxes very difficult. This behavior is especially problematic with apps like Time Machine. I understand that part of this may be due to restricted access of the Mac OS, but it would be great if you're engineers could find a way around this problem, much like you've done with the dock.
- When using several of my Adobe graphic applications, I've noticed that the DualHead2Go is displaying a sort of canvas looking texture for solid color areas of designs I'm working on. This appears to be more prevalent with color builds.
- Normally, I operate my setup with my MacBook Pro closed. Occasionally, I'll have wake from sleep issues, which are only resolved by opening my MacBook Pro and letting the Matrox device reevaluate my setup.
Again, this is a great device and I really applaud your engineers for coming up with a viable multi-display solution for MacBook users, but addressing the issues above would make it even better. Please let me know if you can help me resolve some or all of these issues. For what it's worth, I'm also happy to become a Beta tester for any new PowerDesk software or Apple compatible display devices. I look forward to hearing from you.
