Hi,
I am having a problem with something in the accessibility API causing
a crash in my application when the user clicks in a Mach-O Carbon DB
list view window. I am pasting a small part of the crash log here
below and would appreciate any pointers as to what part of the
acessibility functionality may be causing this. Note that I am not
using the accessibility API in my application but that the user has
turned on all possible accessibility settings in the System
Preferences (I have tried that myself, but can't reprodcue the
crash). After seeing the crash log, anyone an idea which particular
accessibility setting I should focus my investigations on?
