Compiler problem with V C++ .NET version 2003

[Allen Maki]

My compiler is acting up. When I have building error, the left margin
pointer will point to the wrong line. Sometimes, the deferent between the
line that has the error and the line it pointed to can be more than twenty
lines.

Sometimes, It will give error message for something that I commented (//).

As soon as I delete the commented line, the building error will disappear .

I uninstalled the compiler and install it again: I still have the same
problem.

I used to have version 2005, I Uninstalled it and I still have the same
problem.

I recently installed the service pack recommended for this compiler.

I wonder if any body has experienced something like this, before. Or
anybody has an idea; what is the reason for that and how can I fix this
problem; I would appreciate it.
