I hate nothing more than facing mysterious problems during development of a software. Most of the time these problems arise when using Visual Studio.NET 2003. A number of times Visual Studio just stop working. Sometimes when I debug it does not go to the required method. Don't even start me with debugging webservices. During webservices debugging my computer completly hangs up. It really sounds funny but it does happen and its really annoying.
Has anyone of you encountered any mysterious problems?
