Windows Syncing subtitles doesn't seem to work anymore (Eden)

Hi,

In the pre-Eden version, I could sync the subtitles. While pushing the slider left or right, I could see the subtitles change, so after remembering the word they said, I could find the right subtitle.
In the Eden-version this is not working anymore.

I tried to find a buglist to see if this bug will be fixed in a future version, but I couldn't find it.

Does anyone know a sollution to this problem, or if it is on a buglist?

Thanks,
Gijs
