Greeting.

We have a 6 year old application, which contains both managed (C#) and
unmanaged code (C++). For all the new components we try to create them
in C#. We  build all projects (both C++ and C# code) into a solution
from visual studio .net 2003.

In out solution we have a project implementing a pretty complicated
math algorithm. This component usally work very well. But in a couple
weeks ago,  a user found a case that our algorithm did not work
correctly.

We are trying to debug the problem. The odd thing is: when we run the
application from visual studio, it works from both debug and release
mode. But if we run it from the executable file directly (double click
on the exe file from the output folder), the application stop working
for that case.

Any idea what caused this problem? How do we debug our code in this
case? We have run out of the ideas.
