Hi, > Why shouldn't playheadtime include the startdelay?
Because then the values returned are something like this: Elapsed Time/playheadTime 0/200 27/200 65/200 109/200 148/200 178/200 232/232 264/264 It also gives different results to anything that extends AnimateTransform (eg Scale), which would give this: Elapsed Time/playheadTime 0/0 27/27 65/65 109/109 148/148 178/178 232/232 264/264 Thanks, Justin
