We have tracked down why some people are having problems with the patched
7.0 debugger.
This problem occurs only when the patch is applied to a 6.0/6.0.1 debugger
that has had the partition size changed by the user.
By default an application has a 'SIZE' resource ID -1. When the partition
size is changed, the Finder creates a 'SIZE' ID 0 and a 'SIZE' ID 1 that
are copies of the 'SIZE' ID -1 resource. The 7.0 patch for the debugger
modifies the 'SIZE' ID -1 resource and sets the High Level Event Aware flag
(which the 7.0 debugger needs to run). But, because the 'SIZE' ID 0 and
'SIZE' ID 1 resources are not changed by the patch, the state of the High
Level Event Aware flag is inconsistent between the 'SIZE' ID -1 resource
and the 'SIZE' ID 0 and 'SIZE' ID 1 resources - and the debugger hangs when
launched.
The fix is to either:
1) Remove the 'SIZE' ID 0 and 'SIZE' ID 1 resources from the patched debugger.
or
2) Reinstall the original THINK Debugger and run the patch on that
The correct size of the patched debugger should be 84,884
This problem might affect other parts of the system that have 'SIZE'
resources (e.g. TPM) but at this point we do not think so because no other
component has had the state of the High Level Event aware flag changed
between 6.0/6.0.1 and 7.0.
If you have any other problems with components, you may want to reinstall
the product before applying the patch.
