I’ve 3 or 4 Lianja App builder open at the same time…
I have an app to keep my work projects
an app that I would try to sell to a customer
an app builder to peer at the various solutions in the various examples ..
How do you have 3 or 4 open at the same time? Are you running with shared data access?
You reallyshouldn’t be running multiple instances of the app builder.
It may produce unpredictable behavior as it uses an http server internally, shared memory and has exclusive database access.
It also reads and writes settings to one place in your user directory.
in the app builder tables are opened exclusive and in the app center runtime they are opened shared automatically.
