The new 5.2.7 Loch brings all my old .lox files to life. I like the scene:station:labels. Because I'd added lots of station comments to my survey.th data, these are suddenly available, and help to identify where in the cave the wiggly coloured sausage shape is representing. Great work guys. Thanks! Two little things. 1. The default rotation speed makes me dizzy. It spins so fast so as to be un-intelligible. That's not so bad, but it seems not to be possible to make it go slow enough. The range of speeds I find useful are about 2mm either side of the central slider point (out of a total range of 15mm each side) on my monitor, and even with it as close to centre as I can get it with keyboard or mouse it rotates at a comfortable speed, but still too fast for some applications. I'd like to make it really slow sometimes. 2. This may be a bigger thing. The scene:station visibility for entrance and fixed station is based on flags I think, and this is very useful to be able to isolate these parameters. I use a lot of station marks (which I understand are not considered to be flags), as in mark RO42 RO46 RO47 RO49 RO54 fixed to identify survey cairns or otherwise somewhat permanent station markers in the cave (and on the surface). Is it possible to add "fixed station marks" as well as the "fixed station co-ords(?)" already implemented? Hmm, and while I'm at it continuation question marks and comments would be a useful thing as well. And thanks for fixing the map-header bug Martin. I'm looking forward to 5.2.8 to see it in action. (No hurry though) Bruce
