Hi All! I have early '09 uMBP17 and I'm experiencing one of the issues which apparently plagued first TrackPads: when I press a TrackPad it clicks, yet application doesn't register the mouse click. It happens 50/50. If I press harder/hold pressed a bit longer - it works more often. Still very very annoying. I have seen that issue with late 2008 MBPs was resolved with trackpad firmware update (and my uMBP17 has the update already). Has anybody experienced the issue on early 2009 MBPs? MBP17? Is it known problem? Any advice?
