Hello, I'm new to Apple products. I just got my iPad 4 last week and it's great. Just one little thing that I'm just checking if its normal. When I'm in the AppStore searching for apps, when the images are loading and I'm scrolling down the page,suddenly the whole screen will do this weird glitch something pops up for a millisecond and then it goes back and continues loading. I thought it was just a little weird. But everything else is great and it's definitely probably a software glitch. Anyone notice this? Thanks.
