Windows NT Debug Symbols
Setup has installed an icon in the Microsoft VisualC++ 6.0 Tools
program group, that will alow you to install a subset of the WindowsNT system symbols (.DBG) files from your VisualC++ CD-ROM.If thesymbols are not installed, the Visual C++ debugger is not always able todetermine the context of called functions.
For easier application debugging, it is strongly recommended thatyouinstall these files.
See the Visual C+ + Readme for more information.
