--- Comment #23 from Metulski pausenclown_metulski@yahoo.de 2010-08-21 14:23:46 --- I got Metatrader 5 working on "WINE 1.3.1". Network is running, too.
I installed Metatrader 5 on "WINE 1.3.0" and I saved the complete ".wine" directory of "WINE 1.3.0". After installation of "WINE 1.3.1" I replaced the ".wine" directory by the old ".wine" directory of "WINE 1.3.0"
