OK, thanks. Will try out the newest version. I remembered wrong, it wasn't filesystem where it left files all around, but in the Gallery system, all the map tiles were seen as images and it messed the Gallery up. (There may be a way to exclude the modrana directories to be seen by system as places for image files, but didn't then search instructions for it. There were the similar problems in the N900 way back also.)
I did install Qt frameworks also and Modrana kind of worked, but was unusable GUI-wise then.
Some things in Modrana are better then in NavFree so if it eventually will work good in Android, I am sure many Android-users would use it.
And back to the topic, Modrana deserves to be in the Sailfish device also, so thanks for working on it.
