Hi Peter,

:-) I did bad read your message (was morning)

OK, the explication can be...

In VCX are stored class and classlib separatly by other CODE (methods in FIELD methods) and properties values (FIELD PROPERTIES).

In FXP are all information in PRG code.

Maybe is slower finding dependencies between classes.
