Thank you for reporting this. This is a special case in the beta version. We have special kind of self monitoring enabled to catch cases of application freezing.

Would you please describe your environment? System type, database type, database driver used for the connection?
In normal circumstances retrieving large result set should be fully asynchronous unless the driver doesn't support that.

I'm sorry, it's still not clear to me what you are doing when you are getting "application frozen" exception. Are you running a query in the database using SQL Server Management Studio? Or running it from SQL Assistant SQL Editor? Or copying already retrieved results to the clipboard? Something else?

Thank you. This makes sense. While the result set is being copied and if takes a long time, the SQL Server Management Studio becomes unresponsive and that triggers a special self-monitoring exception in SQL Assistant indicating that the application might be frozen. This is a special exception handler we enabled in the beta version. It will not an issue in the release version. Please treat it as a non-error and ignore it.
