LyX 1.6.4.2, another minor service upgrade release, is available now. The upgrade fixes recurring pseudo-crashes when running LyX on Mac OS X 10.6 (Snow Leopard). Apart from that, the release is identical with LyX 1.6.4.1.
Note that the fix impacts the performance on the Mac while autosaving. Thus, the upgrade to this version is recommended to LyX users on Mac OS X 10.6 only.
