>   What's odd is I think this is both an OS level and higher library
> bug(s). Occassionally the entire OS will hang with the mouse cursor will

>   Saving the project, then going to the timeline or video controls to set
> the current playback position, or advance back to the beginning - pretty
> much any change in the videos position = instant crash. If I reload the
> same project after saving it, without changing the current playback
> position, I have no such problem until I save and immediately try to change
> the timelines position (seems to be something with that entire process).
> Oddly enough, I could postone the "crash" by saving, adding a new track,
> then setting the playback position where-ever I wanted. Worked for awhile,
> but then crashed after every save again.

>   On the OS side, i've noticed on a slower single core system (1.8
>   processor), if I click an control or option anywhere in OpenShot (or
>   anything for that matter, ie.,. audacity) and don't allow the previous
>   function to complete... the applications hang. It's like a messaging
>   sync problem with the underlying libraries (doesn't wait for the
>   current function to conplete before attempting the next one).

>   Also, the first video I made with OpenShot a month ago, didn't exibit
>   these problems. It seems to have started within the past 3 weeks
>   (perhaps during the upgrade, or with an underlying library not quite
>   in sync with the layers above).
