I calibrated a map some time ago with version 6 and now I tried to open it with version 7, but the map is fully compressed.
I tried to calibrate it with the 7, but it works only until the program is open. if I close and reopen the program the map is still compressed. I noticed that the map with the version 6 is 2.5pixel while 7 opens it with 80 pixel.

how can I fix this? thx
