I've seen a few quotes that I've wished were blank. But ultimately, no. I haven't noticed a problem myself.
If you were to ask the IT mob here at work they'd ask if you've tried something really technical, like rebooting, in order to fix it. Personally, I find a good old fashioned boot with a real foot, far superior to the new fangled reboot variety anyway. I've found that there is very little that can't be solved with a swift kick.
I think that the Space Aliens are behind this. It's kind of like a, "Crop Circle".
Anyway, I have known for many years now that there are at least 17 species of space aliens who have nothing better to do than hack drumming forums. They sit at their bases on the dark side of the moon and they simply hack away until we are all totally baffled.
