Ok hard to explain this one, it may be the codeproject addin i added recently or its a setting i have changed somewhere but when i'm debugging my app opens up many .cs files, kind of interesting but when i want to step through my code it goes into these files and when it errors it has no reference to where the error actually is. sometimes these files being opened have errors on them which i have had to correct for the code to work.

Has anyone seen this before and what could i do to stop it, i wish to confirm that it is this addon before i remove it (which i will do if it is this addon causing this).
