In the pull to refresh sample, if I freeze 2 columns in the grid, I start having problems when scrolling horizontally.
If the scrolling gesture end in the frozen columns area, the pull to refresh animation is shown.
We have the same problem in our own app. I think that it is even worst when you have few columns and few rows. It makes it very hard to use frozen columns in conjunction with pull to refresh.
Is this behaviour expected? Is there a workaround?
