Hi Experts,

I have a legacy program form which contains only a few components, a button a label and a textfield. These have been changed from the standard Borland components to Developer Express components, so instead of using TLabel we are using TcxLabel etc. There are no standard 'T' components left on the form. There are no references to them in the source, header or form files.

When this form is loaded at runtime, I get the following error:

"Project program.exe raised exception class EClassNotFound with message 'Class TLabel not found'."

If I compile the form explicitly and re-run the program, the error disappears. However, next time I reboot my system, open Borland Developer Studio and compile/run the program, the error returns.

Does anyone know whats going on here? I don't know why the error comes back, but I suspect it's something to do with BDS auto-managing the form file and loading something it shouldn't.

I should note, a colleague also works on this project but never sees this error. We are using exactly the same source/header/form files. I don't know what is different between our two systems that means his version of the program does not see this error and mine does.
