While I was editing some sql, I right clicked on a table in the query and did Open Declaration to see the table details and SQL Developer got stuck on this screen.
I wasn't able to close this and I left it open like this for close to an hour without change. This has happened before, but not very frequently. I've currently switched over to 21.4.1.349 to see if the Oracle Freezing is better.
