>Thanks Marcia! That should do the trick. I'm still confused as to why PEMSTATUS() says there's a Width property on my page when everything else says there isn't. Have you seen that behaviour before?

This classes have hidden properties:

DataEnv : it have all the container's PEMs

* hidden methods for a future VCX support
Writemethod,SaveAsClass :
Header,Session,Column

* hidden Class Designer positioning
Left,Top,Height,Width :
Hyperlink,Relation,Cursor,CursorAdapter,Collection
XmlField,XMLTable,XMLAdapter,ProjectHook

A more general way ( slow )

IF !PEMSTATUS(m.oControl,"nOrigWidth",5) AND TYPE("m.oControl.Width")=='N'
....
