Hi,
When the issue next occurs can you upload the memory dump of the DShow application when it hangs? To do this invoke task manager, select Applications, right click on the DShow application and select "Create Dump File".
Please also attach the output of this tool as soon as possible after running through the above steps:
http://www.displaylink.com/support/ticket.php?id=269
Once downloaded, please run it and select "Gather Support Information"
When you reply please select "Manage Attachments" from the "Additional Options" section below.
From there select Upload and navigate to the output of the tool which will be in a folder called "DisplayLink Support Files" on your desktop.
Thanks,
James
