I also have an alternate Windows version of 0.8.5. It's not entirely the same as the official Windows Sigil package, so I would prefer that issues involving it be posted in its own thread (same with the Linux binary packages). My binaries are completely unofficial. Any weird behavior with them could very well be something
I did wrong when creating them.
So please... if you're experiencing issues using one of my unofficial binary packages, report those issues in the thread for that package. If I (or anyone) can reproduce the issues in an officially supported build of Sigil, then the appropriate action can be taken. Until then, remember that they're unofficial for a reason.
