At the moment the program version 3.4.3 does not remember the actual windows position when i close program. Can i change the windows position and the windows size in any INI-File ??
It remembers only the size of the window (will, if it doesn't it is a bug).
What you can do, is to edit the language file that you use (.lng) and in the [MainWindow] section try to add for example:
MainWindow.Left=100
MainWindow.Top=100
MainWindow.Width=600
MainWindow.Height=400
