drag problem with video seekbar

Hi Everyone,

I'm having problems with the seekbar not working (Storyline 360) with basic slides that have audio and some image animations. First problem is that it doesn't identify the true duration of the slide. Upon completion of the slide it dragging the playhead doesn't to a earlier position doesn't change the position of the visual. In additional pause and play does not control the slide, and rewind does not control the slide. In other words the seekbar doesn't work at all. I've tried multiple approaches to try to resolve this: I downgraded my version to see if this would solve the problem, as the seekbar was working in previous versions. I've changed to the modern play tested without success, and reverted back to the classic player, again without success. I've tried different settings in slide properties and seekbar properties in the player control without success. As any observed this problem with Storyline 360 in the recent versions.
