From: Sven Hesse
Date: Sat, 6 Jan 2007 11:17:20 +0000
Subject: - Fixed cut off and missing sounds - Fixed a crash/static reported in
 the forums (sending Winkle to the vulture) - (Hopefully) fixed the
 immediately-closing notepad heisenbug (#1621089) - Fixed using unitialised
 values after allocating the variables
