It is crude but works. also via script a button could scroll left right to exact horizontal scrolling coordinates and then at each 'page' the table could scroll vertical. The popover part may be ignored and instead just focus on the left right and separate vertical scrolling.

Thanks Tom - that looks good but I don't really want to have separate swipe zones. The behaviour I'm looking for is very much along the lines of that in the Calendar app on the iPhone. Swipe (mostly) vertically and the calendar scrolls up or down, swipe horizontally and it moves back or forwards by day or week.

Turns out that I had the canCancelTouches property of the scroller set to true, so it's no wonder that the touch events weren't being registered. Now that I've got it setup correctly (delayTouches = true, canCancelTouches = false) it seems to behave how I want it to (more or less).

Cheers,

Terry...

I can do this with a pair of touchstart/end scripts but unless the swipe is very horizontal the object scrolls and no touchstart or end messages are sent.

The mouseH sometimes gives sensible values within a scrollerBeginDrag message and other times not - it never seems to return a sensible value in the scrollerEndDrag message.
