Since upgrading to Flash 8, I've noticed a few odd things happening. The main thing is that my cursor now disappears at some of those ads. I wouldn't mind but in Safari, my cursor is disappearing when my mouse is hovering over the tabs when the ads are directly under them. So I have to scroll the page and then select the tabs.
I also notice flash ads not sticking to the page when scrolling. They seem to jitter while scrolling. Not the ones on this site but it must be a certain kind of ad.
On a possibly unrelated note, I've noticed that happening with Quicktime previews when scrolling left to right. They also jitter in the same way. Is this one of the wonderful 10.4.3 'improvements'?
I think I'll go back to Flash 7 for the time being where my cursor was actually working right. I don't know why people break stuff when they try to improve it. Do people forget to test stuff these days before releasing it or what (nano screens, 10.4.3 nvidia drivers...)?
