>The problem persists. Moreover, we found a strange thing: all our classes show the parent class in the classlib property in the Properties sheet. E.g. for example, CalendarObj from aCalendar library shows Calendarobj in the Class property and c:\mmviscollect\libs\abusiness.vcx as Classlibrary property. Is it right? Should not it show aCalendar.vcx instead? Can you please quickly check any of your classes?

The classlib field in the vcx stores the relative path to the classlib. PEM window shows the full path. You need to open the vcx to see what's really there.
