The problem occurs now that my videoproject includes 100+ of clips.

When the frames are being drawn in the timeline the last 10 clips hangs - meaning
i cant play them. Just Black frames/thumbs. If I open my project and scroll an other way through the time line it will be some different 10 clips hanging... Are there some limitations???
