Mike,

Can you try creating a new project from scratch, only add your main and see if it'll build the project up for you.

if that doesn't work...

I think you are down to the worstcase grunt work solution to finding the problem. Copy your whole project and source files out to a safe place.

start a new project putting the lowest level classlibs in first, build, add a classlib, build. Once you get to the failure point, you;ll have to disect that classlib one class at a time until you find the class with the error.

>I tell you, this one seems to really have me beat. I tried Mike Yearwood suggestion (code that compiles classes and prints errors in the selected project). His code gave me a long list of errors. If I try to compile classlib individually and focus on ones that I have made recent changes to, I do not get an error. When I try to build, I get the "line too long" error and it kicks me out of the build. I also took your suggestion David and looked through many memo fields in the classlibs, but I did not see anything out of the ordinary. I thought I would post just a little more info here and see if it generated any new ideas. I did transfer my files over to a new computer and I tried to mirror the tools/options settings that were on my last computer, but maybe there is another setting that is causing the problem. I would appreciate any help.
