1.7b3 DisplayLinkManager 85% constant CPU

[jconley]

Have noticed since 1.7b3 + Lion that the DisplayLinkManager sometimes gets stuck processing 85% CPU for long periods of time.

I have nothing on the displaylink display, or the adjacent display (except desktop backgrounds)

Unplugging my displaylink adapter makes it go to zero, however will resume at 85% when reconnected.
Quitting the process in activity monitor will make it go back to normal. (it auto-restarts itself)

On a side note, why aren't all the displaylink processes 64-bit yet?

Thanks for your report.
A fix that should address this issue will be available in the next beta (coming soon).
If it will not be fixed in the next beta, please let me know.
About 64-bit, not all the processes would benefit from being converted to 64-bit at the moment, maybe in the future.

same thing here with high CPU %, looking forward to the next beta soon!

Could you please test 1.7b4 driver and report if the CPU usage is still there? Thanks
