There is a small bug in xboard-4.5.3a, on OS X 10.7.3, using the gcc-llvm 
compiler supplied by Xcode 4.3: 

Windows slide exactly 4 pixels to the left from session to session. That is, 
open some windows so that there is a margin to the left on the screen. Then 
quit, and start another session. Then all new windows have moved exactly 4 
pixels to the left relative to the position from the previous session.
