Glad I could help you, Hans.
There are two great programming highlights since time immemorial: once Linux and of course SweetHome3D!
The result is a law of the universe: who's able to use SweetHome3D on a Linux-System, will be happy!
And of course I will try to make as many people happy as possible by showing them how to use SweetHome3D on Linux.
A humble servant of the universe
