Hi,
I just installed rc2-27. Editing the first schematic (from 9.0.1) it looked like I wasn’t able to save as the “*” mark for a modified file in the title bar didn’t go away. However, the status bar showed that it did save on CTRL-S. On reloading the (correctly saved) file I wasn’t able to recreate the issue.
So it’s sporadic and in a sense cosmetic, but I thought I’d pass on the observation.
