Hi.

I own a 15z and till now have been happy with it.  When I'm at home, I attach a Logitech Wave MK550 setup, ASUS 24" monitor (HDMI) with speakers, and a USB3.0 hub.  When I'm at work I attach a standard USB mouse and monitor (both Dell by happenstance, the latter with an HDMI adapter).  In either case every 5-30 seconds some process would steal focus from the current working window.  This made productivity untenable unless I disconnected the wired mouse or wireless antenna.  After looking through the threads below, especially the lengthy one here: http://en.community.dell.com/support-forums/laptop/f/3518/t/19386509.aspx?PageIndex=4, I uninstalled the Cypress driver and then the Quickset driver.  Only after removing Quickset does it appear that the behavior stopped.  I'll try re-installing the Cypress driver and see whether the behavior restarts.

If the behavior does not come back, does that mean Quickset is at fault?  If it is, will Dell work on a new driver to solve this issue?  Given the laptop I chose, I needn't express my dissatisfaction with a partially working system.  As marginal as the service is I miss my eject button and it sticks in my craw that, again IF this is the problem, I can't use the whole system in a reasonable fashion.
