When I open two Query Analyzer windows in rapid succession, the first window opens correctly and starts loading, but when the second window opens, I get an error:
Unhandled exception has occurred in your application. If you click
Continue, the application will ignore this error and attempt to continue. If
you click Quit, the application will close immediately.
Object reference not set to an instance of an object.
I am opening the two windows from Enterprise Manager, by first selecting a server group in the tree-view pane, then for two servers, selecting the server name in the detail pane, and using the Tools/SQL Query Analyzer menu.
The detail portion of the error message:
See the end of this message for details on invoking
just-in-time (JIT) debugging instead of this dialog box.

************** JIT Debugging **************
To enable just-in-time (JIT) debugging, the .config file for this
application or computer (machine.config) must have the
jitDebugging value set in the system.windows.forms section.
The application must also be compiled with debugging
enabled.
For example:
<configuration>
<system.windows.forms jitDebugging="true" />
</configuration>
When JIT debugging is enabled, any unhandled exception
will be sent to the JIT debugger registered on the computer
rather than be handled by this dialog box.
