Connection window disappears when cancelling a connection (4243105)

In the connection screen, if you try to connect to an existing connection (by double-clicking it and with save passwords option unticked), then cancel it before the login step, the entire connection window disappears, as opposed to just the smaller window asking for the password.

Steps:

With 'Save Passwords' option unticked:

1. Open Toad
2. Go to New Connection screen
3. Double-click on an existing connection in the list
(The new smaller login screen appears asking for the password)
4. Press Cancel
5. The smaller window, and main Connection window disappear.

If you do the same steps, but press the 'Connect' button instead of double-clicking it, the issue cannot be replicated.
