Multi-Touch drag/select not working after sleep

Hello,

I have a new Penryn 17" mbp and I am experiencing some weird issues.

From time to time when it comes back from sleep dragging windows and selecting text with the trackpad no longer works.

I can double click, single click, two fingers right click ... except the drag and select does not work (it works if I use the button but not with the tap-drag).

The only solution is to reboot the machine.

I had multiple mbps (15" CD, C2D, 17" C2D) and never had this type of issue.

There is nothing weird in the logs.

I tried everything I can think of:

checked unchecked drag in conf panel,

enable disable bluetooth (both usb devices could have conflict) even left BT off.

deleted hibernate file (could be corrupted).

reset PRAM, VRAM

Even reinstalled Leopard from scratch (no backup)

Nothing works.

I tried to unload/reload trackpad kernel extension but does not work and completly disables the trackpad until reboot.

I would really hate having to take my new mbp in for repairs especially that I know how they work on them and how long they would keep it.

Anybody else has this issue or know of a way to reload the trackpad driver so I don't have to reboot every time it happens?

Thanks.

Well it could be a week or a month you never know for sure.

Is just that there is a chance they scratch it or they do some other stuff to it or even worse they replace it with a refurb.

 

ok found a work around but still no solution. Is definitely a software issue (trackpad driver) could be related to xcode/iphone sdk.

I see this in the logs:

19/07/08 12:20:31 AM /usr/libexec/hidd[25] IOHIDEventQueueEnqueue: Error enqueuing memory. (0xe00002e8)

I just found out that if I do:

sudo killall hidd

it restarts the hidd service and the tap-drag select is back.

at least I don't have to reboot.

Anybody has an idea why is this happening?
