I'm having a problem with two AN24X0 devices on a Leovo Thinkpad W500 with XP.

On starting certain applications (including a lot of the system utilities, but not browsers, email or GIMP) the screen flashes constantly and the mouse is moved to the center of the screen every second or so. After 5-10 minutes the application eventually starts up - afterwards often one or both the Displaylink devices will be in 640x480 mode, and cannot be changed via display > properties.

Have tried various 4 and 5.0 and 5.2 drivers with the same behaviour, and also get the same with both the Intel and ATI graphics on the W500.

A single device works fine. The same setup worked correctly on a Dell M65.

Any help or suggestions appreciated. Would one of the newer Displaylink devices help?

Thanks.
