Old but new: "Database is locked"

[cnewtonne]

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?
