Hi Ajak,

did u ever used symbol servers to download symbols or is your symbol server
set in the _NT_SYMBOL_PATH is dead?
if so, see whether you have _NT_SYMBOL_PATH in the environment variables, if
you have one, delete that temporarily to test.

because if the correct symbols are not found then every time, the debugger
will try to download the symbols and it takes time every time you step
through.

or if some other problem try these steps

1) Disable any addins if you have any
2) devenv.exe /safemode /resetskippkgs
3) devenv.exe /resetsettings
4) check all these things, even if it is slow with all these steps taken,
5) try some tools like filemon, to verify whatz happening when you debug.

HTH,
Ram
