I've opened a project, click on a class library only to find that it is apparently empty...I just clear all, close all, etc etc and reopen the project and it's all fine. HTH

>retrieved the class library. but I am not exactly sure what happened. when I noticed the class was damaged I removed it and added it back. It was still damaged so I removed it and copied a backup copy into my classlib then added it and it still showed damaged. At the same time I was sending the last message VFP got a krnl exception. I shut down my system and started it back up and the class library is in tack or as it should be. That worries me.
