--- Comment #7 from Vincent Beers VincentBeers@gmail.com 2009-05-24 15:36:07 --- In Wine 1.1.21, no$gba only remembers the last opened directory until the program's closed. If the program is restarted it defaults back to the SLOT directory while the Windows behaviour is to stay in the previous directory.
