Apologies Windows users, but a buggy version of libxml2 accidentally made it into both of my Windows installer packages for Sigil-0.9.11/12. Users will experience "entity doubling" (Linux users will remember this issue). One entity in Code View will be doubled in Preview. After saving the entities might be doubled in Code View and quadrupled in Preview... you get the picture.
This is easily fixable without modifying Sigil's sourcecode and without needing to make a new release. I'll fix the Windows installers and re-upload them to the 0.9.12 release page tonight. I'll let you know when it's safe to re-download and install. My apologies.
