Mike,
I've never seen this error popup before. And it might be one of those errors that really isn't too indicative of the root problem.
I would open your recently changed classlibs as tables and browse the Properties and Methods memos looking for "oddities"
You could take a programmatic approach and alines() each of those memos and check the length of each line. In properties set via the property sheet make sure you aren't doing strings that exceed 254 characters.
I'd do the same things to your prgs etc.
>I tried compile classlib on the classes that I have make any recent changes to and have had no problems. I did not check them all, but I do not know why the others would have a problem I also tried to compile my forms and did not have a problem there either. Build EXE with or without the compile files checked still gives me an error "line is too long."
