I really like the Combo Touch, but have suffered with the issue since I had one. I think I’m finally making some progress though. I think the essential things are to make sure that your firmware/software are up to date, and any auto zoom settings switched off as described in the other messages. However, my latest find is you can recover back to the normal state by turning the ipad to vertical (portrait mode) and then back again, and then you can avoid the zoom altogether, at least in safari, by not taking your cursor to the very top of the screen. At least for me if I take it to the very top, it instantly zooms in, but then I can recover from it by turning the ipad to vertical and back again. Also, I realised that this problem only seems to happen when the keyboard is plugged in.
