Hi Eyvind,

I have seen this before. You get this when adding a pageframe within a pageframe using the same class. You can work around this by creating a second pageframe class and adding it.

>In a form of mine, I am trying to put a pageframe within another pageframe. At run-time, the error message "Cannot add XX. Class definition is cyclical" shows up. The error is easy to reproduce; just create a form as a class, and add a pageframe within another pageframe on it. Note that the pageframes must be subclasses of the base classes that vfp provides.
