I've been working on a project for several months now, and had been using an older version of GSAP for animations, largely to scroll the site up and down to specific sections when the user clicks the navigation. I recently updated from beta 1.5 to the latest ( 1.8.2 ) and noticed that the site no longer scrolled properly: the scroll animation will start and get about 20-50px and just stop.
This only happens in Safari/ML 10.8.2. I used BrowserStack to version test, and Safari 6.0.2 in Lion works just fine.
To debug, I set an onUpdate function to log the $( window ).scrollTop(), and it seems as if the tween fails at setting the window's scroll, but continues to run fine:
I was able to solve my problem by just reverting back to 1.5, but I wanted to send a bug report.
