Highlights running slow on latest version??
 

I've upgraded to version 2.219 in he last week or two, and I've noticed that the words and/or the highlights are running slow on certain songs.
I didn't notice it before I upgraded, but can't be 100% certain.
On some tracks, only the highlights are behind the music, but on others, the actual words were hardly on the screen in time, let alone the highlights!!
I know there is a playback offset in the tools menu, but that only delays the highlights, not advances them.
Has anyone else come accross this? Or am I just going completely barking mad? :t
