DisplayLinkManager.exe priority should start High, not Normal
On my Windows 7 x64 computer, in times of heavy CPU usage, the mouse cursor becomes extremely choppy. This is because DisplayLinkManager's priority is the same as that of the process using all the CPU time.
I have found that if I set DisplayLinkManager.exe to High priority, the mouse cursor remains mostly smooth. Please consider defaulting DisplayLinkManager.exe priority to High at startup. This is an easy change in code and would solve one big irritation with this product.
