Displaylink crashes Java

[karel]

Freshly installed Windows 7 64 bit on a laptop. All updates applied.

After installing Displaylink and getting my 4 external screens to work, any application that uses Java gets an APPCRASH. Even starting the Java Console crashes.

Both with Windows classic and Aero. Both in Firefox and IE.

What can I do to fix this?

Additional Information

When starting the system with two direct screens (without the 2 Displaylink USB adapter screens) all works fine.
Starting again with the additional 2 displaylink USB adapter screen causes the Java to crash again.

System: W7 home premium 64 bit, Intel Integrated grahics + Nvidia GeForce GT540M, all latest drivers including displaylink.
