I believe that happens when the searcher clicks on your ad on page one, than moves to page two and clicks on your ad again. I think that counts as one impression, but 2 clicks.
Does anybody else have another explanation?

The 200% ctr happens when the servers haven't updated.
The server handling the Clicks is reporting the actual clicks, but the data for Impressions is lagging, thus you receive the 200% ctr. When the data eventually catches up you'll notice that the 200% is now back down to earth.

defanjos, thats not how it works :)
It's a matter of time lack between the impressions and clicks. I once had an add runing with 300% CTR - but look again in a couple of hours and you'll get a more correct picture
