I dunno, DR White, it works smoothly on my desktop and I don't have mobile devices to test with.

You could try adding lock / unlock screen to the snippet and see if that alleviates some of the jerkiness, or lockScreen,

Code: Select all

on mouseDown pButtonNumber
   lock screen
   grab me
   unlock screen
end mouseDown

bogs,

Using Lock/unlock screen doesn't help in mobile.

I am sure that there must be some way to make it move smooth in mobile.

Thanks,

David

Huh, the dictionary says it works on mobile.

Hmmm. Well, if it doesn't, hopefully someone that does mobile will show up shortly.

Bogs,

It does work on mobile. I have used many times and does a great job preventing screen update, until all the screen changes have been made. But, it does not help the jerkiness when using "grab me" in mobile.

I am SORRY!

The Jerkiness is only seen when I test the app on the Simulator. When I actually downloaded it to my phone it works fine.

Again sorry to bother you,

David
