Depends on the videocard in your computer. On a high end system like Klaus is using, everything is just fine. On my somewhat somewhat outdated Dell 1240x1028 monitor with a 75Hz verticalscreenchange frequency I see some jitter when I turn KRPANO/PTP flash pano's but no clucks. The card can keep up but the monitor can't. Now that is the problem with all work you do for the net Graham, you never know what you'r gonna get (and what your client uses) at the other end.
By the way you have some parallax issues as well and you should use manual shuttertime and manual white balance (or shoot raw then you can set any WB you like).
