This patch fixes a bug in popupmenu.library 10.10.1. The bug generates random memory trashing at library expunge, potentially locking the system up. First you need to determine which library version you've got installed: 1> version file full libs:popupmenu.library popupmenu.library-000 10.10.1 (03.05.2001) ©1996-2001 Henrik Isaksson If the version is other than 10.10.1, you probably need to get pmlib-10.8.6-fix.lha instead. If the version is -000 10.10.1, you can proceed. Next, patch the library: 1> cd path:to/pmlib-10.10.1-fix 1> spatch -olibs:popupmenu.library-fixed -ppopupmenu.library-000.pch libs:popupmenu.library If no errors are output, the patching succeeded and popupmenu.library-fixed file was generated. Now replace the old file with the new: 1> rename libs:popupmenu.library libs:popupmenu.library-orig 1> rename libs:popupmenu.library-fixed libs:popupmenu.library Reboot. - Harry Sintonen
