I've moved my Thunderbird mail from Windows 10 to Linux Mint 19.1. Everything's moved, and account logins are all working, but the Reminders window is always on top of the other Thunderbird windows now. Current Thunderbird version is 60.7.0. I can't tell you what version I was running on Windows 10, since I have done a clean install to get the disk partitioned the way I wanted. I've looked at the Preferences/Calendar/Reminder tab and didn't see a setting that appeared to affect this behavior. I've also looked through Preferences/Advanced/Config Editor, and didn't see anything that looked likely there either. Left Clicking on the top of the Reminders window shows that Always on Top is unchecked, which points back to Thunderbird. Were is the setting? I'm just not seeing it. -Thanks
