--- Comment #36 from Jörg Höhle hoehle@users.sourceforge.net 2010-11-17 12:34:20 CST --- David, It may not be necessary to file a bug report about Chip's Challenge any more.
Given today's commit 129778803ec4a72e05665acee761da0d0c461efa (+ the part of the preceding commit that moves setting MCI_MODE_STOP prior to sending out the notification in the MCI player) that app now works well enough with MIDI. There are no more hangs in the menus when BGM is enabled. MIDI music now plays when a level is started, as well as when resuming from a pause with F3 or when the window lost focus.
However MIDI does not always play. If that happens, move to another level and it usually works. You may still compare it with native: please file a *new* bug if there, MIDI always works - every time.
