[Therion] Diving data, limit 8 lines for lox?

hi all (again) This has been puzzling me for hours For the diving data attached (now very simplified as I tried to work out what was going on) Uncommenting any consecutive lines up to 8 and the lox output works, any more than 8 and an output is produced but it does not open, the loch flashes on the screen then vanishes. one of the none working Lox file also attached. pdf and 3d files are produced from the full set of data I am on Ubuntu 10.04 therion 5.3.5 loch 5.2.8 I am now giving up for the night, it has not been a good session Andrew
