And only intermittantly of which it should be absolutely never. The purpose of the ClassLoc field in the VCX is to state this is the parent....EXACTLY, not almost or most of the time and by the way it is ok to use another class of the same name in another VCX in the same folder if you want to sometimes compiler.

Actually I can't because this is the first form that is being migrated into new framework. The rest of the forms are in production.

I could rename the new but that would screw up the future.

I was hoping that I would learn something I was missing here but it looks like I am dealing with a bug that has been here since 6.0 and will have to change something on my end (Folder, parent name as you stated) report the bug and wait for the fix.
