I encountered a very strange problem. The very presence of 
\definetextbackground changed the meaning of \midaligned (and 
\rightaligned). Attached are the minimal example that illustrate the 
problem. The first file, nobackground.tex has no background and works 
as expected. The second file background.tex has a textbackground and 
\midaligned is no longer middle aligned.

Any insight into this strange behaviour?
