Hello,
I am running the trial version at the moment (using XP Pro SP2, German). It runs all right in an account with administrator rights. But in an account with user rights it won't terminate correctly. An alert appears (Title: Sudoku) with the following message: "Zugriff auf eine unbenannte Datei wurde verweigert" which translates to something like "Admittance to an unnamed file has been denied". The programm cannot be started again, unless the Prozess "Sud.exe" is terminated manually in Program Manager. Is this behaviour a bug or due to the trial version? I will not buy the Programm if it can only be run with Administrator rights.
