Yes, I have the same. After I saw it blinking away and explored what it might have meant. I have ended up just downloading an "Update" thinking it might be the cause. But still, it Blinks away.

I watch this question with interest. I'm far from being a "geek" but really do have problems with this computer language that gets used.
