Oh no, sorry to hear that you’re having trouble with the app! I was able to reproduce the issue that you’re seeing with your main blog on Windows–I’ll spend some time digging in on it and see if I can get a fix out this week!
I’ve added the Windows version of the previous release (1.2.7) to the list of available downloads. If you should have a free moment, could you test with this version and let me know if you run into the same issue? This will help me to determine if the problem has something to do with the refactored code in 1.2.8.
