The subject runtime error is:

Error: A runtime error has occurred.                              Do you wish to debug?                              Line 51.
Error: The callee server is not available and disappeared; all connections are invalid. The call did not execute.

This behavior can occur if a 3rd-party pop-up blocker that prevents frames or tables from loading is installed on your computer.

To workaround this issue, disable the 3rd-party pop-up blocker, or if it allows, temporarily disable the blocking functionality.
