From 9f33b3abbeb211182e92cebb13c8c6d1175468e9 Mon Sep 17 00:00:00 2001 From: Max Horn Date: Sat, 1 Nov 2003 01:17:15 +0000 Subject: [PATCH] possible fix for bug #833854 - I rechecked the assembly, there actually is a check for box flag 0x20 in there. However, that flag has a differeing meaning in older engine versions, so I put a version check in and updated the comments.
