Ok. First, I downloaded xControls2.zip, as I was still using the original
xControls modified by Greg.
The problem is that there is a slight semantic change, documented in the change
log for 0.70.1.
The Control routine, when called with the classType action, should return a
class, no longer a family. The change was needed in order to emulate controls
that don't belong to an actual family, like RichEdits for instance.

The cure is to change the return values accordingly:
* in HSplitter:168, change WINDOW to Window
* in HSplitter:180, change WINDOW to Window
* in FileBrowser:116, change WINDOW to Window
* in DatePicker:176, change WINDOW to Window

After doing this, validId() crashes because it is passed an id of {-1}, which it
does not expect. These {-1} are components of managed controls cx and cy. Greg,
any hint?
