Thanks, that solved that issue.
It appears to be working fine now but with two problems
1) The animated text links do not move in a straight line as they did initially but in a random way in between the start and end (not in Animate but when previewing in browser).
2) The animation does not stop but keeps looping. I deleted the Action for the animation to stop and inserted a new one but this still does not stop it.
I get the messages:
"* AntiAlias is not supported in HTML5 Canvas document, and has been converted to CanvasFonts in an instance of Text."
and "WARNINGS: Frame numbers in EaselJS start at 0 instead of 1. For example, this affects gotoAndStop and gotoAndPlay calls. (6)
Classic tweens that end on a keyframe with multiple elements may have unexpected results.
Modifying the transform point in a tween can produce unexpected results.
Input and static text fields are published as dynamic text fields.
Content with both Bitmaps and Buttons may generate local security errors in some browsers if run from the local file system.
Motion tweens are published as frame by frame animations. Use classic tweens where possible."
Perhaps these are related?
