I will try mi best.
1.- Yes they do, it's anoying to have to do that everytime I edit a Unit, but if done it keeps its location.
2.- For the position boxes, I have to use perior "." Or 2,36 becomes 2.
For the range boxes, I have to use a comma "," or otherwise the system ignores it and gets really big ranges. 1.55nm becomes 155nm for example.
3 and 4. I have had no problems with that fields.
Also, I'm unsing simplot V2.0.0. Build 230
Really thank you.
Alejandro.
