2.1 beta better than 2.1 release
 

I run a MBP Pro mid 2010 with an Apple Monitor at the Mini-DVI Output and 2 other displays (LG and LOC) with 2 Displaylink USB adapters. Version 2.1beta works, 2.1 release not! Although in the beta all monitors are synched after booting and have to be be separated each time to work properly, the system can be set up properly. On the release version, the 2 USB-monitors usually do not show up, sometimes one of the two does.

Yeah. I gave up and grabbed a dualhead2go dp from craigslist. Works awesome and very reliable. Too bad.

The flickering is quite bad with many apps, particularly Chrome with rotating banners etc.
