I just spent a few hours on an iOS app where i was using Grab to move a large, 2-4mb, photo around.
Was jerky, until i realized that the scroller was accounting for the jerkiness. Found a way to do preopenstack before and after that moving process (killing reviving) the scroller. Can grab photo and spin it around now. Is there a scroller? Are you on iOS? sims On Wednesday, October 9, 2013, Earthednet-wp wrote: > Folks, > Thanks for the comments.
