Ebay anti-sniping program?

[71-LS6]

Here's a little question for you guys with more Ebay knowledge/experience, than me.

For the third time in a week, using two different computers, I have watched and attempted to bid on some low dollar listings ($0-$200). All three times, with less than 2 minutes left, my screen was frozen and I either did not get to update my bid (once), or place my bid (twice). In each instance, I would have bid higher. I am using a high speed cable connection or my WIFI connection. My M.O. is no different than what I always do. Did they implement some sort of anti sniping program?
