Thanks, Hawke. At least there is someone else on the planet that is getting the same problem as me. It's annoying. Gareee....the problem occurred with Neftoon Pal, so I loaded up good ol' standard David but still had the same problem with the runaway Export sub-menu (as per the pic). This time I selected the "Wavefront OBJ" entry at the bottom of the menu, and it worked. So I re-loaded the Pal, and did the same and got the same result. So the work-around is to select the entry at the bottom of the menu. NOW .... With all due respect to most other comments in this thread .... please quit hijacking this thread !! Could you please either stick to the topic, or open a separate thread ? I did not intend this thread to be about misbehaving spotlights or switching between preview/render modes etc.etc. Also, point-blank comments along the lines of "well it works for me" just aint helpful.
