Hi, Matthew, Thanks for the response to my question. The example you reffered to is very instructive and I will follow that approach trying to alleviate the instabilities I've experienced. I did run a VI from a machine that has LV installed, but how 'complete' that installation is, I am not sure how complete it has to be (i.e. what is considered 'complete'; maybe it's not a most comprehensive installation, but certainly it had the core part installed). I will further try to download the lates version of the Run-time Engine and see if it helps anything. Finally, I did already download the evaluation version of the LV 7.0, trying to test stability of my VI under 7.0. It still crashed multiple times. However, I read a comment of one of your NI colleagues that concurrent presence of LV 7.0 and some older version of LV on the same machine can work unstably. (I admit that I did not remove the older version just to test this VI under 7.0. Maybe even LV 7.0 does not resolve the issue about 3D Surface Graph?)
Thanks. I'll keep you posted if I observe anything new about this. Miro
