I don't know exacly why, but the solution I introduced in the last
message works for the centered mathboxes (I think that's what "display
math" means), too. So just to be sure we are talking about the same
thing, I've attached a LyX-example-file.
Would be grateful, if you could tell me why it works.

PS: There needs to be the \newsavebox{ggbox} in the document header, I
don't know if this is part of the lyx-file or of my environment.
