Wall, nice debugging, but you should list the software, since it does conflict with our specific hardware/software/windows integration in the G750... whether it is their fault or not, if it is to be avoided till they fix it, it would be nice to know - would save us the same or other problems on our G750's.
There have been people with unresolved touchpad oddness, and I don't recall anyone mention trying to remove anti-virus software, or even mentioning what anti-virus they have installed... it might just be that was their problem too.
I uninstalled the McAfee software that came with the G750JH, and installed Norton Internet Security, and so far I haven't had any problems, if you are looking for a replacement.
Thanks Wall!
