Just found the following at the SuSE portal pages (German only): http://portal.suse.de/de/content/reports/tax2001.html
Rough translation on the introductory paragraph: The program t@x by Buhl Data has been around for the Windows platform for some years. This year, the current version T@x2001 has been made available for the Linux OS for a first time. In order to do this the Windows emulator Wine was used. Wine allows using Windows applications running Linux. This emulator has been modified to work with t@x2001.
The summary as far as Wine is concerned: The program should be more stable and faster.
Does anyone know which modifications were made to wine?
Ciao Jörg
