Old but new: "Database is locked"
 

I have been relying heavily lately on using markdown files by inserting a template item with 'md' extension. Hitting control+j, causes UR to open externally using Typora editor. As I continue to work in Typora, UR keep emitting these messages. I can click OK and continue to work externally. It does not appear to affect anything.

Why is UR returning these error at some interval. Can it be avoided?

Not sure, could possibly try disabling multi-user mode.

Beyond that, we would need to be able reproduce the problem in order to investigate further (which we haven't had much success in doing -- https://kinook.com/Forum/showthread.php?t=5684).
