... <-- working now, well so far.

I had mine back but gone again. Upong further searching two possibilities which I don't hold too much hope for.

1) A wee spritz of WD-40 in the headphone jack hole.

2) Trash Quicktime and reinstall.

I'm doing 2 since I cannot find any WD40. How the hell does that happen? I had maybe six cans of the stuff scattered through the house and shop. I'm about to panic with a hurricane approaching. At least I have plenty of duct tape and Bag Balm.
