then disabling the BG.

leave it on all the time?

yes, I think? In previous version navigating this timeline will nearly
instantly lead to crash due to libpng/libtiff/openexr being feed  with
wrong image.

in new version you just get some chatter in terminal and black compositor
window, so you stop bg render, start it anew, play with fader on video
track a bit, park playhead at beginning and then re-creating of brender
files actually starts, but with long enough timeline you still can outrace
this process by mousing playback cursor around fast enough.

Anyway, try wild things!  earlier we get crash info - the better (even if
not for  tomorrow build due to time constrains)

3- Closed and restarted CinGG; created new BRender in tga: all OK.
