Hi ChrisMartin
I think this is a known issue that is covered in the release note.
This problem occurs on XP with any applications based on the
Windows Presentation foundation graphics subsystem.
These applcaitions can cause the issue you are seeing when more than 1 DisplayLink adapter is connected to the PC.
We are still looking at a fix for this, however there is no simple fix due to the way the WPF interrogates the graphics drivers on a system. This is why it is taking some time to fix this issue.
Thanks
Wim
