Rom 9 Apr 2006
- Bug Fix: Add a check to stackwalker so that if it detects it is running on
Win9x it'll switch over to the Win9x compatible dbghelp.dll. After
checking it out, it doesn't require any changes to the stack walker code
as it has the 64 bit function exports. So all that was required was
just changing which DLL was used to get the function pointers.
- Bug Fix: Upgrade to the latest stable debugging tools from Microsoft.
