For a long time, the proc ID's for all the System-defined windows were always
less than 256.  Although there was never any "promise" from Apple that they
would forever remain that way, evidently FB assumed that such was the case,
and allocated only 1 byte for the proc ID information.

Luckily, there is no such limitation for FB buttons, which is why we we're
able to use the newer controls (like disclosure triangles) in the BUTTON
statement.
