Yes I have had this issue however for me it seems to have improved with the 1.9.11 update. I had been experiencing the "tap - no page change - tap again - go ahead 2 pages" every 5 to 10 pages a few weeks ago. It was so bad that I didn't like to use my Touch. I like to look up into the distance on a page turn (to rest my eyes) and so I often missed whether the page had turned once, twice or not at all. Talk about confusing!
However since updating I have only had a couple of double turns in about 5 books.
What firmware version are you using?
