moltens

I think it was since I was not using the newest version, I recently updated and figured I would be good for a while. It was crashing while using the old saved project file so I had to export what I had done and work after that on the newest version! 

The title says it all. When editing, the "Sequence Preview" window used to watch the video freezes on a frame while the audio keeps playing. It only happens during preview, whenever I export it it turns out fine but it isn't worth the hassle to not be able to see what I am editing, please help.
