Multitasking tray sometimes activates even with a single-click

So I've been noticing a rather strange issue on my iPhone 4. The multitasking tray sometimes activates even when I just single-click the Home button.

Is anyone else experiencing this too?

Ok. Tried restore, no change. Its like 1 out of 10 times but still very annoying.

No one else having similar issues?

Same here. Every so often multitasking tray opens with just one click as well.
