Following a tip in VFUG Tips and Tricks, I have saved (as a class) all of the controls from Page3 of a PageFrame to CasePg3.vcx. The file exists. I added it to the app's Class Libraries, recompiled all. I added the following code to Page3.Activate():
IF THIS.ControlCount=0
THIS.AddObject("CasePg3", "CasePg3")
THIS.CasePg3.Visible=.T.
ENDIF

I get Error 1733: Class definition CASEPG3 is not found. But it IS in the app's default directory. What am I leaving out?

TIA.
