Jaromir, I have successfully updated V7.0 table columns using 1e-008 instead of 0.00 to prevent divide-by-zero problems. On the other hand trying to use Geomapvector.MBX just now produces that error even though none of the columns which it is supposed to be using have zeroes in them. Please post any other such "tiny number" experiences your acquire.
