Checked in these mods today - threaded loading on timeline so that if you have 2 or more CPUs (which by now everyone probably has), the audio tracks will be loaded at the same time as the video track.  Before the program would load the video track, which takes a lot longer, and then serially load the audio tracks.  Because of threads, now the audio tracks will be done loading way before the video finishes.

Also, boxblur layout fix was provided by another's work.

Thank you RafaMar for your feedback in checking yesterday's mod.  And looking forward to next month's chapter (I added Chapter 9 to the forum notification for others to easily view).
