a) Done by the skin. Obtain a skin display using 
Skins.Current()->DisplayWhatever and use that classes methods to alter the 
content
OR b) Open an OSD yourself using the cOsdObject class
OR c) Only use menu pages with single line items

Must be done by a) (inside the skin) or b) (using cOsd-functions) or c) 
(Clearing the menu page / setting an item's text)

Didn't find anything similar to this, yet. You can get the "would-be" value by 
dividing Setup.OSDWidth by the former value of cOsd::CellWidth()

Skins.Flush()

Done by deleting the objects created by a), b) or c)

Depends on which of a), b) or c) you choose, I guess...

We all know that, and there will _always_ be more countless hours of 
frustration when versions change, but that's evolution :-)
