Anyone else having click/tap problems in iOS 5?

I noticed that trying to tap some dialog boxes in Safari on my iPhone 4S are a bit harder than before, or impossible to click successfully.

For example, replying to a YouTube comment was much easier, the 'reply' and 'post' buttons would actually work and click in Safari on iOS 4.

But with iOS 5, a lot of buttons aren't working such as those and buttons on Apple's website for reserving an iPhone for my dad.

Please help or provide your thoughts on this.
