In Visual Studio 2003 the C++ debugger expands structs and classes and displays the first three members automatically. This makes tooltips etc much more useful, but for some classes and remote debugging this can really hurt debugger performance.
You can disable this auto-expansion by adding an item like
in the [Autoexpand] section of autoexp.dat.
This works for VS 2003 only (and the related Xbox debugger).
