My WPF applications frequently crash while being debugged in Visual Studio 2010. Fault module always points to dlumd32.dll, a DisplayLink library.

Checking "Enable unmanaged code debugging" would sometimes give the following errors:
Sometimes it freezes up the whole computer including the mouse pointer. The screen would update "ever so slightly" every 3-5 minutes so it isn't a complete freeze... but it's ultimately unusable and needs a hard reboot.
EDIT: Tried the following; didn't help.
- No monitor connected to USB adapter.
- USB adapter not plugged in (drivers including dlumd32.dll still loaded).
- Disabled switchable graphics; use dedicated ATI graphics.
- Disabled switchable graphics; use onboard Intel graphics.
