Can't change data types in design view

[MissM]

I need to change the datatype from text to OLE object to store
an image. All files in the db are closed except for the table that
needs the change. I've noticed that it won't let me change ANY
datatypes on any fields to anything other than what they are
(text).

What to do?

Never mind. Closed and reopened db, bingo. Who knows, but then who cares?
