I'm using Tero Hietanen's version (0.6.2-8zs.chinook) on the latest Diablo update (N800) and I can confirm that after switching away via the home button, one cannot return to it and eventually the system reports the launcher as unresponsive. Force quitting the launcher does not quit the game itself (the game, music and all, is still running in the background), but it can be killed from the command-line. I recall someone above mentioning one version where app-switching did work: what changed?

Otherwise, the game works great. I have not tested the SuperMelee net-battle yet, but may this weekend...

Thanks for the porting work!
